633-814 25 GB 6X Blu-ray Logo Top Single Layer Recordable Disc BD-R, 50-Disc Spindle

As long as they're Optodisc these burn great, although sometimes only at 2x and not 4x or higher

I have only used a few, but no defects so far. The media is HTL, so it may be inorganic, but no official info. The reflectivity is better than other HTL and the write contrast is much better than other blu-ray discs. It registers quickly when inserted, a good indicator of readability. My recorder will write these at 8x, and they are officially rated to work at 8 to 12x speeds depending on the recorder - great speed! I have now burned 100 discs. I had 2 defective discs, very reasonable for a cheaply priced product. They work just fine on the four players tested, included an old flaky player that has difficulty with many discs.

So far so good. 16 burns, no failures. Using Pioneer BD209, and BurnAware Free, at max speed (in this case 7x to 7.4x). I will definitely order these again... soon. Update: Make that 36 and no failures. Update 2: I'm now into the second order of these disks without a coaster. Add to that a consistent burn speed of 7.2X, and you have a winner. Not enough time has passed (a few months) to determine data retention, but will check back if I have a problem. Update 3: 3 packs down, still no failures. I'm impressed. Update 3: Second spindle done. 1 failure (my fault). Great product. Ready to reorder. Final Update: Wow, These are a fantastic value. Several spindles now without a problem. 7x burns, not a problem. Data retention after 1 year, 100%.

Good

Work well with no glitches.

I have burned over 150 now working towards 200 on a Pioneer Blu ray using Img Burn. I like HTL or the darker recording surface as it's supposed to be better for longevity. I am converting most of my movies to mp4 for quality and smaller size, I do have a SFF pc connected to my big screen tv. All of the Vampire Diaries series fit on 4 blu ray discs. I am however trying some SmartBuy blurays as they are $9 cheaper and are supposed to be HTL. Guess I'll find out in 2 weeks when they get here. If they aren't, or if there is a problem, I'll be back to these.

Good quality disks - two burned with no issues. Quality appearance with logos, including the Blu-Ray logo, and has write speed and available space on each disk. I like the white label, because I use a black marker to label the disks, since paper labels sometimes cause imbalance. However, there was shipping damage due to inadequate packing, see picture - the cover was broken. 4 months later, and still no response from shipper. (after 2nd purchase in Jan, 2026) 10/12/26 - 9 months later and still no response from the shipper.

Update - my original review was actually for the printable white top discs, so updating here for logo top. The logo top discs so far burn much more reliably. I am about halfway through a stack of 50, and have had no failures yet. However from what I have read of other reviews it does appear that there is a quality control issue with this brand. I probably will not order it again. Update 2 with musings - So after several more disk burns I've had only one of about 30 that had read failures after a "successful" burn. Looks like the stacks I received are a good run. However, the experiences others have had, as well as my own experience with a printable top set, of stacks with 50% failure or worse leads me to conclude that buying this brand is a bit of a crap shoot, but with better odds than craps, since most people seem to get good discs. So when deciding whether to buy, I suggest you check your horoscope or whatever you do to evaluate your potential luck level, and avoid this brand if it looks like a bad day for you.

Very good disc to burn and to write on themselves I am very satisfied

I use these for archiving data files for graphic arts. They burn very reliably, seldom any writing problems or wasted disks.

I have countercheck with the disk from another source which more expensive but give a 100% burn success rate, it seems that no point to save a 30% cost but end up 50% of the disk not usable with all the time wasted on keep trying.

Haven’t had one fail during burning process. Plays smoothly.

Excellent product, work great, n9 problems so far.
