Video Game, CD, DVD, Blu-Ray Repair Machine 110V - USA, CAN & MEX Only

I've tried several of these CD Repair Machines through the years -- all the cheaper ones, of course. Hand crank models. Small electric models. All with lingering issues and, mostly, tedious to use and not with completely satisfactory results. This is the best unit I've ever used and it's because of the powerful motor and self-contained design. I will not go into all the esoteric accolades and complaints that everyone else has already posted. I will simply say if you are an old-timer with 700+ CDs in your collection (I started buying CDs before I owned a player -- and that was the year they were introduced!), and if you are shocked by the condition they are in as you attempt to convert them to MP3 or other digital transportable formats -- then know this: a) Those CDs are completely recoverable if the "damage" is only on the silver side; and b) this is the repair machine you definitely want when you have a lot of CDs to recover! A $35 or $50 hand-crank unit is not going to do it for you. At least, not satisfactorily. If you are just starting out to convert your CDs to MP3s, you will find -- as I did -- that the conversion process is far more sensitive to scratched surfaces than the music players are, themselves. A CD that might seem to play "just fine" will not allow itself to be copied as easily. If your recording program is reporting lots of errors, or rebuffering repeatedly, or rescanning 3 and 4 times -- it's time to bring in a unit like this to save those CDs. If you only have a few in such a condition, then buying a new CD or the MP3 or iTunes version may be a better choice. Here are some Tips and Observations for use once you've bought this... a) I do not know why they call the first polish you use "Solution #2" and the second one you use "Solution #1" -- but they do. Solution 2 is a little thicker than Solution 1, so be aware before you squirt Solution 1 all over the place. b) Does this unit get a little messy? Yes. But not terribly so. And it's all contained within the unit so long as you are not crazy enough to open the lid while it's spinning the buffing pad and CD! 8-) But my Tip about using a Credit Card helps with this. Note: There is no avoiding getting your fingers messy as you remove the Buffing Pads from the machine and replace them with the next one. So get over it! c) The instructions for spreading the polish across the face of the buffing pad "with the tip of the bottle" are somewhat useless. The tip of the bottle is really not the correct shape to do this well. Squirt a few dollops of paste here and there on the pad, then use a Credit Card to spread the polish evenly. It gets easier as the pad gets used more. A dry pad absorbs more polish -- a used pad absorbs less. You do not need to cover the entire inner part of the pad up to the small hole because the retainer cap that locks the CD in place will cover about 1-1/8-in diameter from the center out. You do want to concentrate more on an even coating out to the very outside edges of each pad, however. Yes, this takes longer, but the results are vastly superior. d) Once you run your CD through Solution 2, I do recommend you heed the mfr's advice and proceed with using Solution 1 for the best results. That is a light aqua color and should be applied to the second buffing pad. You will notice that this polish is the one that gets flung about more because of its viscosity. e) After you are finished with Solution 1, remove the CD, and its locking cap. Then peel the Buffing Pad away from its turntable inside the unit. You'll notice a line of paste that has been flung against the inner walls of the machine. Carefully scrape off that goop with your Credit Card and reapply it to the Buffing Pad that has Solution 2 on it. This is all valuable paste and should not be discarded. NOTE: At first, I was reusing this paste on Buffing Pad 1, but that aqua polish is the finishing touch and needs to remain as pure as possible. Using the excess paste on the Buffing Pad with Solution 1 on it will degrade the final polishing. I switched to using it on the Buffing Pad with Solution 2 -- and although it discolors that white paste over time, it is a better choice. Mark the pads with a Sharpie if you start getting confused. Keep the Aqua Paste Solution 1 as pure as you can. f) If you must resort to using the actual 3M Sanding Discs for deeply-scratched CDs, you may wish to discard the excess goop that you scrape off the inner walls. I have not had to resort to these discs so I cannot swear if their sanding surface creates a gritty residue. If so, you might wish to discard that goop. If you have kids and they abuse these discs, I can see that the Sanding Pads might be very useful. g) While you have the Locking Cap off, and are preparing to insert the next CD, wipe off the bottom of that Cap so it can seat against the next CD properly. Don't let the goop fill up its threaded screw area, or under the Cap, itself. I did not find it useful to count just how many CDs the first bottles of polish might recover because some CDs have deep scratches and need more polishing than others. So, your mileage may vary. I had a few that required 2 passes. And if you don't always use Solution 1, then it affects how much of that polish you use, as well. But I got quite a large stack resuscitated, so far. I have not actually finished either bottle as I write this, and have not refinished all 700+ CDs in my collection. Also, the Wiping Cloths that come with the unit really should be replaced with Microfiber Towels. My method was to rinse my CDs in a sink and then pat them dry with Microfiber -- not a hand towel or paper towels (too coarse). Do not use paper of any kind -- not toilet paper or napkins. These are all too harsh and will scratch surfaces. This system is NOT complicated. Everything about it -- except the motor housing, itself -- is built around commonly-available supplies. The Buffing Pads are similar to 3M "Perfect-It" pads @ 4-5/8-in Diameter. The Sanding Disks are 3M discs. Even the two polishing solutions are available by other mfrs. So don't feel trapped by JFJ. Their prices are probably as competitive as anyone's, however. The trick is, don't buy more solution than you'll need, as the polish (like most car waxes) may get gummy or watery over time. It will not store indefinitely. If this item seems too costly for you, consider these points: You can waste a lot of money buying tools that really are not suited for the job. And you probably have. If you own 10 CDs that need polishing, then buy the hand-crank model. If you have over 100, this unit will serve you better. You can always sell it, later, because these are quite popular and well-respected. If I were a shop selling used CDs, I'd set one of these up on the counter and offer to clean 2 or 3 free for each customer -- they'd buy it after seeing the results. Swirl marks are almost invisible. The mirror-effect is very nearly as good as a new CD.

At the time of this review, I have been using my JFJ Easy Pro for about 6 months, so I'm going to write a review from the point of view of a novice users who bought this product with no prior experience of using a disc repair system. However, a used record store which I frequent owns a more expensive JFJ machine and allowed me to pick their brains for some valuable operating tips. I should also mention that I have at this time successfully repaired several hundred discs. I have not used ANY of the sandpaper pads, the #1 Blue polishing solution, or anything else supplied with this machine other than the #2 White solution and the foam buffing pads. That's because this combo will repair 99% of discs that are worth repairing. I frequent garage sales, thrift stores, and flea markets, looking primarily for music CDs to expand my collection. I dont't usually waste my time or money on discs that are so bad they would need to be sanded, though I can imagine if you were in IT for example and had a really destroyed data disc you needed to recover, it might warrant use of some other repair strategy, for me the White Solution + foam pads are all I ever need. Choosing discs to repair: The data layer on an optical disc is near the "top" of the disc - that is, the label side, just beneath the label. That's how this machine works - there's a thick layer of polycarb on the non-label side which can be polished to remove scratches on it's surface without affecting the data on the disc. So most discs which don't have damage to the data layer can be fixed. Simply hold the disc up to a strong light. If you can see daylight through any of the shiny areas of the disc then the data is damaged and you will not be able to fix the disc 100% no matter how much polishing or sanding you do. As an aside, optical discs are read from the hub first and out towards the edge, so the first track on your CD, for example, will be located nearest to the center of the disc and so forth. This gives you some idea where to look for that scratch which is causing your disc to skip or your DVD to lock up. This machine is simple to operate. There's no real need to "practice" as some reviewers maintain - unless you plan to use the more radical sanding options. Here's tip #1 from my record store friends: Get a spritzer bottle of water and moisten the foam pad before each use. Don't soak it, just get it damp and then apply the white solution. I apply the solution to the pad in a ring and then spread it out to the edges with my fingers. There is a 1-1/4" patch in center of the pad which doesn't need solution on it - this corresponds to the hub of the disc which doesn't get polished. Next, attach your disc to the spindle on the lid. The clear, non-label side will face down when the lid is closed. Here is another very important piece of information that my friends warned me about. BE VERY CAREFUL SCREWING DOWN THE DISC! Make sure that the plastic screw, which is threaded somewhat imprecisely, doesn't get cross-threaded, so that the disc can wobble ever so slightly when it is being polished. This is the source of the cracked disc hubs that other reviewers have mentioned. So use both hands to press the disc down absolutely flat against the top surface, make sure it hasn't gotten hooked on the screw threads, and then carefully and gently screw on the nut that holds the disc in place. If it doesn't go on easily, back off and try again until it does. Once you've got it on right, tighten it down good and finger tight. Now you're ready to polish the disc. Watch a movie or something. Put on some headphones because this machine is pretty noisy. Keep a rag handy to wipe the compound off of your fingers if you're going to be doing a number of discs. Remove all the discs from their cases at the beginning, so you don't have to handle the cases with polish-covered fingers. Now, using the #2 polish and a foam pad as I do, there's no risk of over-polishing a disc. If you just want to remove finger-prints etc, a single two-minute run will be enough. Otherwise, I have found that giving all my scratched discs three two-minute runs for a total of six minutes of polishing works best. I don't add more compound between runs. Most discs that are not repaired after this time are not salvageable, but if your really really want that disc, you can try another six minute set on it. Note that this machine will get hot, especially if you are doing six minutes for each disc, so keep an eye on it and give it time to cool off every now and then. If the nut has gotten too hot and you can't loosen it to remove the CD, I have found that a spritz of cool water will usually loosen it. After polishing, it is safe to stack the repaired CDs on top of one another, and even to put them aside for later washing. The compound will not "harden" on the discs. To remove the compound, I take a batch at a time into the bathroom spread them out on the counter label side down, then I put a drop of dishwashing liquid (non greasy, like Dawn) on each disc. I run some very warm water and using my fingers I wash and rinse the discs and then stick them inside the folds of a cotton bath towel to dry. Here's another tip from me: Make sure you get all the compound off the disc, especially in the central hub are, which often has a groove around it in which the compound can remain. If you don't get all the compound off, it will smear around your disc when you give it the final touch up. For me, the touch up is nothing fancy. Like I said, I don't use any of the other equipment or sprays you are provided with this kit. I just dry the discs off and look for scratches. There are some advanced scratch removal techniques you can employ at this time which involve spit, your fingertips, and a white cotton T-shirt, but these are not part of my official recommendations. :) Here are a couple more non-official non-recommendations which are sure to void your warranty, so try at your own risk: Meguiar's Ultimate Compound (Car polish) is almost, but not quite as good a JFJ Compound #2, and quite a bit cheaper. It works! After you've polished a number of discs, you will see a lot of gunk inside the machine which is made up of used compound, tiny worn fragments of foam pad, and presumably, tiny bits of poly carbon. This can be scooped off and re-used as buffing compound as long as you're using a spritzer bottle to keep everything moist. Just smear it all back on the pad. (Update: I wouldn't do this if you have used the sandpaper on any discs!) BTW I have repaired several hundred discs at least, and have only used the original two foam pads that came with the system. Neither of them has completely worn out, so I think you can expect to get a couple hundred uses at least (remember I do SIX MINUTES! per disk) out of these pads - IF YOU KEEP THEM MOIST. In summation, this is a great product, works exactly as described, and has been a boon to my CD collection, enabling me to scoop up and refurbish many rare used discs that others simply pass by. Like many such tools (like ink-jet printers for example) they really nail you on the supplies, however. I hope my tips will prove useful and help others to mitigate this at least a little.

I’ve been using the JFJ Easy Pro for a few months now, and I can confidently say it’s one of the best investments I’ve made as a reseller and collector. I’ve successfully repaired over 100 discs so far—everything from DVDs and Blu-rays to PS2, Xbox 360, and even some old GameCube games. The machine has easily paid for itself by salvaging items that would’ve otherwise been unsellable or unplayable. Performance & Results: The results are impressive. It handles light to moderate scratches with no problem, and even some heavily scratched discs have come out looking nearly flawless after a couple of cycles. Games that were unreadable now load perfectly. I use the buffing mode with polish for lighter jobs and the repair setting with sandpaper pads when a disc is really damaged. I highly recommend using a higher-quality polish like Meguiar’s M205 instead of the stock compound it comes with—it makes a noticeable difference in the final finish and doesn't clog the pad. Ease of Use: The learning curve is pretty minimal. Once you get the hang of applying the right amount of polish and knowing how long to run each cycle, it’s pretty much set-and-forget. The included manual is helpful, but I also picked up a few tips from YouTube and disc repair forums. Maintenance & Durability: After over 100 discs, the machine is still running strong. Just be sure to clean the pads regularly and replace the sandpaper when it starts to wear down. The motor seems sturdy, and the overall build feels like it can handle serious long-term use. Tips for Best Results: Don’t overuse the sandpaper step—it’s powerful, and you only need it for deeply scratched discs. Always keep the pads clean and fluffed for a smooth finish. Let the disc cool down between cycles if you're doing multiple passes.

I never updated this again, so here it is. As per note below the machine sparked out after 27 days. Still under warranty. Sent back, told I would have new machine by a certain date. Passed. Called again, would that there was a delay due to defective units. Finally got my replacement unit. The unit itself has been great. Again the paper towels are worthless, I bought microfiber clothes as another review suggested. A problem I have found, as noted below, is that the white polish is inconsistent. The white polish I got with the replacement machines were both great. I had ordered a few more bottles, no problem. The latest one is bad, has separated as warned about. I have also noticed that any heat will make it worthless, heat seeming to be anything over about 75 degrees. For the most part I like the unit and the products that come with it. There are issues, but for the most part it does the job decently. For this reason I have upped the rating to 4 stars. I will leave original review below on original unit I purchased. After I had given up on 1st unit purchased I sold it. After a number of months I decided to try again. 2nd unit arrives. After practicing on 3 discs I had it down. Now I know that the white polish on the first unit was bad. Also I never used the paper towels provided, I purchased the Endust for Electronics Microfiber Towel. Still not as great and simple as some claim and the video shows, but works quite well. NOTE: 27th day after purchased, had only used on 3 days (about once per week) for a total of about 30 discs, the switch sparked out and machine died. It would seem that I have poor luck with these machines. Original review: I bought this item based on the reviews on Amazon and I have to assume that either most of the reviews were written by company employees or I got defective polish and cleaning cloths. I went through at least 30 discs and each one was worse than when I started with it. I tried different methods and times after reading reviews on Amazon and elsewhere, and watching the video on youtube. Every disc ended up with dozens of scratches or more. Note on cleaning cloths: I compared one to a regular paper towel and the paper towel did less damage. Again, maybe I got a bad set of supplies, but after a bunch of discs destroyed while completely following the instructions this machine doesn't do what the company claimed.

If you're looking for an exciting, entertaining way to bleed through your Blu-ray library or if you have someone, in your life, that you really don't agree with, I'd highly recommend purchasing this product and using it on your collection. The device comes with step-by-step pictorial and large-print instructions. If you follow them to the letter (as I did), there's a good chance that your Blu-ray will either not load (can't be read) or actually make it WORSE than it was. I imagine you need to evoke a little bit of creativity when following the step-by-step instructions, because if you follow along EXACTLY what it says, you have a 50/50 chance of getting the results you want or having to jump back on eBay or Amazon and order a new movie; or in my case, 0% chance. I tried to remove minor scratches, blemishes, and smudges from 4 different Blu-ray discs, as they were causing pixelation and frozen screens. Applying the right amount of compound, in the order which to apply the first compound (enigmatically labeled "#2"), and ensuring I had a snug fastening of the disc, I ran the machine for a minute: product recommendation for the first pass of the buffing process. Then, per the directions, it suggested if you want a nice finish and shine, as well as additional protection, you go with the second (blue) compound (bewilderingly labeled "#1"). Then, using the micro-fiber cloth included in the kit, I gently wiped away the remaining compound. Making sure there was no trace of compound left, I put the Blu-ray into the player, and waited, and waited, and waited until the player eventually ejected the disc with the message "disc not readable." Trying it out a couple more times, it repeated the same error as it originally did. Disappointed, I thought it was just that one disc. So I put in another. And another. It was like I was a gambling addict at a slot machine shoveling quarters in and believing that I would eventually win big. All in all, I now have 4 Blu-rays that will either not play or has a worse picture than it did before I tried buffing the disc. I stopped there because I decided a little pixelation here and there isn't that bad compared to losing an entire movie/TV-series. I will keep the machine as it makes a great paperweight and is a very ingenious and creative way of damaging slightly blemished discs; but if you value your collection and can live with a little skipping in movies here and there, then save your money or buy a whole new disc.

I recently purchased a couple of large used CD collections for my reselling business, and quickly realized that quite a few of the discs were scratched and scuffed. Looking for a cost effective solution, I came across the JFJ Easy Pro+ and after reading up on it, I decided to buy one. The unit arrived well packed in a sturdy box with styrofoam inserts. Inside the box you get the resurfacing unit, a white buffing pad, a yellow polishing pad, and two black sanding pads. You also get a small bottle of the white buffing solution #2, and small bottle of the blue polishing wax. Along with these items, you also get a small spray bottle of anti-static spray, 3 coarse sanding pads, 3 soft sanding pads and a cloth for dealing with the mess that you will make. There is also a well laid out instruction booklet that gets your started. The manufacturer recommends you practice on 4-5 discs you don't particularly care about before jumping in to the serious restoration work. I will say, I did one practice run before getting started on the stack of discs that needed restoration. Needless to say, it's a fairly straightforward process and once you get started it's mostly common sense. Having said that, there are certain things to be aware of: There's no getting around it, this is messy work as you're applying the two solutions, and you will get your hands dirty. It is also time-consuming work. Even though the machine is doing the work, you have to be nearby to switch out pads, add solutions and change discs over. It's not something you can set and forget. You need to be available to switch things out. I found myself going through the two supplied solutions at an alarming pace, and ended up ordering the next size up. Even now, I seem to be going through solutions faster than I should. And the supplies are not cheap. The pads also seem to wear down quite quickly, and I have had to reorder those in order to keep moving forward on the discs that need repairing. The good news is, the machine does what it was designed to do. You can definitely transform ugly looking discs into very presentable copies. Having said that, don't expect miracles. It will not resurface discs to the level of multi-thousand dollar machines, but given its modest price it does a far better job than it has any right to. Most people would be very happy with the results this machine gives you. In conclusion: it's well worth the money and it should pay for itself in short order.

I just got mine today and have to give this thing 5 stars considering the price and that a really good resurface machine is about $2000. With that in consideration the way pro plus really is a very good machine if you read the directions and simply use some common sense. Use one buffing pad for solution 2 only. Use the second pad for solution 1 only. Do not mix them up. One will stay whitish from using solution two amid the other one will be blue from using solution 1. Also since you get two sanding pads do the same thing. Use one for coarse and the other for fine. I actually was able to stick the label from coarse and fine into the center of the sandpaper after applying them to the sanding pads so I never have to get them mixed up. After doing this you simply put in the sanding or buffing pad you want for the job. Now on to consumables. I found out quickly from my first couple of jobs that it is much more economical to do a batch of discs at a time and do it in assembly line fashion. I set up 3-4 discs and after if they are in similar condition I simply do one at a time using buffing pad with solution 2 then done. For the tough jobs, do the same thing. Line up a few and sand them all using the same grit sander, then after all are done. Wipe the discs, then switch to buffing pad #2 and do them all with that. Then again with pad #1. This way you are able to go faster as you aren't switching pads multiple times as well as saving solutions since when you run a job, a lot gets flung onto the sides of the machine inside. Simply wipe that off after each disk and apply it to your pad when you put on the next one. You'll be good to go and running like a well oiled machine in no time. This saves you a lot of time and money on solutions. Anyway, I hope this helps people thinking of buying this. It's an excellent machine as long as you understand how to use it and what for. If you don't intent to do a lot of discs, I'd say ship your discs off to get fixed and save the time and money. If you're like me and starting a game collection or starting to sell, then this is Great starter machine. Also please keep in mind, as the directions state, the machine will shut off if the motor reaches its thermal threshold. This happens to me and I had to let is sit for about 15 minutes today. The machine itself didn't seem very warm, but I had been running some really damaged discs that needed some serious sanding for a few minutes and I'm sure the 4-5 1 minute cycles caused the motor to get close enough to shut off to protect itself. It's not a problem with the machine or a design defect, this is simply not a volume machine. For me, if I ever get the the point that I need to do a lot of these then I'll have probably reached the point where a $2000 azuradisk will make sense then. For now, for the 10-20 I'll probably do each week this is a perfect economical system and I really couldn't be happier with it. Money well spent, just do your research and make sure this will really meet your needs. Again, this is really a small volume home or very small business unit. This is not something for a large business or someone with a very large collection as it will be frustrating to wait for these cold own periods. If your in that boat, look into an azuradisk or similar industrial machine that can handle your capacity. I hope this was some helpful information for someone looking. Again. It's a great little machine and it totally does what it says and I can see the quality in it. It's sturdy and well built while being lightweight (plastic mostly). For a little over $100, it really is a steal considering how much you'll save not having to repurchase games, movies, etc. good luck and enjoy.

I watched several videos and read online reviews before making my purchase. I also know that a lot of my local retro game stores use this same machine to resurface their discs and I have been very happy with my purchases there, so I decided to get my own. The JFJ Easy Pro works very well with both resurfacing and buffing discs. At first, the instructions looking somewhat intimidating as there are a plethora of pictures and instructions, but once you read through everything and give it a try, it becomes pretty easy after only a few discs. The machine itself is pretty straightforward. You open the lid, unscrew the locking nut, attach the disc, insert the necessary buffing pad, close the lid, set your time, and away you go. The sponge buffing pads are easily cleanable due to the buffing compound being water-based. After so many cleanings, the pads will become hard and encrusted with dry compound, so using a little liquid soap and rinsing with water just like a sponge makes them clean again. Cons: The only real complaint I would have is that the description says that the 5oz. bottles of included buffing compound will do about 100 repairs. Truthfully, I’d get the package which includes extra supplies (it’s twice as many pads, buffing compound, cloths, and sanding discs), and it only costs about $15 more. The only other issue I encountered was while buffing double-sided discs. When you attach the disc to the plastic mounting plate, the graphics side faces the plate while the blank side will contact the pad. However, because there is no artwork on a double-sided disc, it requires one side to always touch the plate, so if that side is already scratch-free, it can become slightly scratched again. So naturally, you’d have to turn it over and buff it out, but then you risk getting minor scratches again. This isn’t a really big deal as I have found a cheap and easy remedy to this. I bought one of those eyeglass cleaning cloths and placed an old junk CD on top of it. I used an ultra-fine point marker and traced both the outer edge and inside hole. I cut it out with scissors (you’d be surprised how difficult it is to cut even with a razor blade) and when I buff a double-sided disc, I first place the cloth over the spindle, then attach my disc. Problem solved---no risk of scratching. I wouldn’t use anything like a rag or felt fabric as it may cause scratches. Use only something that is scratch-free. I would recommend you stay away from all of those other cheap off-the-shelf or “As Seen On TV” disc buffers as they will only remove light surface scratches, or some don’t even do much at all. You get what you pay for, and this is definitely a product worth its price. It pays for itself in the long run and gives you peace of mind when buying discs at yard sales or thrift stores where that may be scratched. I definitely recommend this machine to anyone wanting to buff their own discs or for friends.

El equipo de restauración JFJ , realmente funciona y me permitió recuperar varios DVD que tenía de colección de hace más de 20 años y estaban afectados con manchas en la zona de información , utilizando el equipo y siguiendo las instrucciones apoyado en el material suministrado (soluciones 1 y 2 así como las esponjas ), el resultado fue 100% satisfactorio.

大きく傷ついたDVDを補修することができました。他の修復機ではできなかったので、重宝しています。

Ne avevo h a che si era bruciata dopo tanti anni di lavoro! Il venditore è stato disponibile! L’ho chiesta con la spina europea e fortunatamente ce l’aveva così! Veloce nella spedizione! Rende i dischi come nuovi se là si sa usare! Io sono anni che la uso e con la praticità si impara a capire come e cosa fare a seconda dei graffi che il disco può avere! Non va bene per giochi ps4 Xbox one o superiori perché sono un’altra tipologia di dischi ma volendo c’è il pezzo apposta anche per quelli vendibili separatamente

My first 10 disks I was only able to get 1 or 2 working out of luck. There was always a ring in the center of the disk and I eventually learned it was being caused by my soft sandpaper not being directly centered on the pad. This causes the side of the sandpaper to scratch a ring into the disk. Once I replaced the soft sandpaper I was able to get 10/10 disks working now and I can even go back and repair the broken ones. There is a learning curve but the product is the best for the price and with enough practice it will make most disks almost scratch free. Obviously there will be some minor scratches left but what do you expect when your sanding a disk? The reason it gets 4 stars from me is because of the price for supplies you need.
