Amazing Product!!
I have been using the Flex Belt and Flex Mini for approximately 4-5 weeks now. I tried several other similar products side by side and the superiorty of the Flex belt Brand Products was astronomical. The construction of other products is quite flimsy or non anatomical, the power sources are not consistent and don't deliver the range and variety of power input that the Flex belt brand products do. Other products are not as form-fitting and comfortable, nor do they give you the sense of a real full muscle contraction with the possibility of a variety of workout selections that feel natural to the motions and contractions that normal exercise would produce. While wearing the flex belt and the Mini product for toning up the buttocks, I immediately noticed significant muscle contractions and extremely rapid initial results. The initial results primarily consisted of a true feeling of a very intensive workout, feeling the muscle soreness that one would feel a day after vigorous exercise. Over a week or two, I actually noticed when I put on an old pair of jeans for the first time, that I almost felt like Kim Kardashian for a minute. I was immediately struck by the incredible amount of toning I had achieved in my gluteal region, which was quite a surprise with the short amount of time that I had used the device, but also, I was surprised that gravity could be so easily overcome in such a short period of time. The teardrop sagging of my lower gluteal region was clearly lifted and there was an overall significant increase in the fullness of my buttock area. The flex belt in the abdominal region had significantly flattened my stomach and I could feel improve posture overall and just a generalized increase in core stability. I also had access to replacement pads that were sold buy a different merchant which were significantly inferior, not sticking to the Belt the way that they were supposed to and not delivering an even pulse of electricity and uniform contraction over the surface of the pad. In contrast, quite surprisingly, despite an addictive utilization of the Flex belt and Mini, I found the original brand name pads to be extremely durable and to last longer and through more exercise cycles than anticipated. I am extremely pleased with the quality and performance of the product and plan to continue to use them regularly to maintain and improve upon the results have already achieved.

Two caveats about this excellent product!
I've used a TENS unit for years and am very familiar with the electric sensation this unit provides. I must say, however, the Flex Belt is far better constructed than I imagined and it fits comfortably around my 38" waist. It's also very thoughtfully designed with various programs and settings. The ability to recharge the control unit without replacing the battery is also a plus. You can also replace the rechargeable battery, when needed, or the entire control unit if it fails. It's all very modular. Others have covered the effectiveness of using this belt and I concur with their observations. My abdominal muscle tone has improved considerably after only a few weeks of daily use. I'm most fond of program #7 as it provides intermittent crunches that really grab you. I definitely give the Flex Belt five stars both for its design and effectiveness. Two caveats I thought I'd share: first, if you clean the oil off your skin with Windex or other household cleaner prior to use, the pads will retain their stickiness far longer. I've been using mine daily for a month now and the pads feel almost new. This should help with the overall cost. Adding conductive gel does work, and is inexpensive, but you are left with residue on your skin that must be cleaned off with a solvent, like Goo Gone. A fine mist of water on the pads also helps with conductivity as they age. Second, I had hoped there was a way to arrive at the higher settings more quickly. I'm now using 120 and getting there takes some time in increments of 1. There is a work around, however. If you push the "+" keys then lean your thumb back slightly, the settings advance by 10 instead of 1. I didn't see this function listed in the manual but it was a welcome discovery. If you hit the information key by mistake it seems to pause things so it can be a bit tricky finding the sweet spot, at least initially. Overall, highly recommended!

I have no excuses for not taking 5 minutes to throw it on!
This belt is not inexpensive (Everything in the box is titled SLENDERTONE. Which also happens to be about $100 less if you buy that belt instead...Not sure if I didn't research enough, but from what i can see, a cheaper belt might not get all the glam and offer the same thing in the end), and it's true that it will not replace normal dieting and exercise. But it DOES stimulate your muscles while your moving around doing other things. I'm a single mommy, so my time is strictly 7-8 am mommy duties (maid, chef, nurse, best friend, disciplinarian, teacher, and chauffeur), 8-5 pm Administrative HR in front of a computer, then 5 to 8-9 pm is back to mommy duties (see pervious list). This belt adds some exercise to my lack of "me" time. Normally there is a weekend work out here and there but it's not enough to really make much of a difference. Dieting is hard and can be expensive to stay strict to, so adding something that I can feel the burn with while folding laundry is really awesome. It is not the most comforatble thing to get used to but I'm a scardy cat and have gotten it up to level 40 intensity in my first 2 trys of the belt. Cons: *The belt is very similar as a belt that is $100 cheaper, and has the same name on all the products inside the box. Wish I would have bought the other belt. *The middle "ab pad" that goes on your tummy doesn't let off any charges until you get the belt up in the 20 intensity levels. I thought mine was broken for the first try and was very upset, but choose to try it again before I sent it back. The hip pads worked great from level 1 and seem to be more intense through the entire experience. *The gels pads are a tacky gooey subtance, the residue and small chunks of the pad tend to stay behind when your done with this device, even with delicate care. *If you are large the pads might not fit where you need them to via the booklet (both hips/lovehandles, and tummy). I am 150lbs, 5'5", and wear a size 9-10 pant. My weight is well spread over me just not toned (which is my mission). The belt right now is at the max pad spacing that is offered, and it just bearly covers the electric nodes that the pads transmit to my body, while fitting in the right places. If you have a larger belly, the pads may only cover your stomach regardless of how stretchy the belt is. *This belt is not inexpensive (Everything in the box is titled SLENDERTONE. Which also happens to be about $100 less if you buy that belt instead...Not sure if I didn't research enough, but from what i can see, a cheaper belt might not get all the glam and offer the same thing in the end), and it's true that it will not replace normal dieting and exercise. *The pads are expensive. Pros: *It DOES stimulate your muscles while your moving around doing other things. Not having enough "me time" to hold a steady gym trip or exersize video, this belt makes me feel like I'm doing right by my body while I work. *The belt can be used by larger ppl as it has an extension piece (I don't need it but I'm sure this is a bonus to some). *This belt is well made and stays where you put it. * There is no noise invloved and no shocking effect to other people or items while using it. This is a plus so I can move and interact with my daughter while exercising. Or watch a movie and not disturb anyone else. *The remote has a timer. So pick your level and let it go for the program you choose. It will beep when it is finished to let you know you have reached the end of the session. The programs are different time intervals and intensitys to mix your workout up a bit for your muscles. *The remote that is used for this belt can be used with the other products (I think there are arm belts, and butt/thigh belts as well), not having to by all the hardware again might cut the price a bit. I hope I was helpful to anyone looking into this product. I don't think I'll be returning the belt. And since I can use it everyday without haulting life, I have no excuses for not taking 5 minutes to throw it on for 20-40 mins a day. You can really start to feel the burn and muscle exhaustion after you get in the 30's, and it goes up to 150. I'm sure I won't get to that level but it's definately an added part of my toning process now! I'll wait and see what this belt can do for my tummy, and I might get the butt/thigh belt next if in a few months I notice a difference.

Not worth your time nor money
I have a lot of lower back pain and was hoping this could assist me with building core strength. My experience is that this does not work. I felt the sensation, no problem. Reviewers who state that they didn't feel anything, I'm really surprised because I definitely felt it - it's a bizarre sensation! Every time I used it, I would use it longer and at a higher strength until I maxed out and I still felt no relief from back pain nor tender muscles as if they had been through any kind of workout. There was literally zero benefit for me. I thought if the belt could strengthen my core, even the slightest, it would be worth it. I finally mustered up the motivation to workout via rowing machine and that did the trick in regards to back pain. Paid a pretty penny but I'm not a workout in public "type" so it fits my needs perfectly (in addition to the physical benefits). You can hope this works. You can convince yourself that this works. People with success stories or beautiful, shiny muscles can try to convince you that "this really does work" but it doesn't. Save your time. Save your money. No miracle belt here. I thought it was worth a shot and now I'm here to tell you to get that out of your head. It's really not.

ONLY REVIEW IT IF YOU OWN IT, PLEASE!!
I am so tired of reading 1 star reviews from non-users of this item! Get a life! Say something if it is relevant to the PRODUCT. I purchased this belt, and I am very happy with it! I suffer from many health issues, including fibromyalgia and hypothyroidism. The rest is too much to list. I cannot do situps or crunches, because of the pain that attacks my entire body, due to the fibromyaliga. I have weight I cannot safely lose, even though it was gained due to hypothyroidism while on a healthy diet. Before my first week of using this product had passed, I could DEFINITELY FEEL a tighter, firmer abdomen. The appearance was subtle, but it boosted my self image, and kept me going, HAPPILY, with the belt. I wore a tunic, leggings, above the knee boots (flats,) and a belt when I went to a salon I have used for more than 12 years now. ALL of the stylists asked me how I had lost weight! I told them I didn't lose weight. I was just tightening up some tummy muscles. They knew my health issues, and asked if I had joined water aerobics or anything like that. I gave them the info on the Flex Belt, which they looked up immediately. One stylist purchased a Flex Belt on the spot. She uses it while she cuts and styles hair now. She swears that her firmer abdominal muscles have significantly helped ease her back pain, from being on her feet all day at work! I am looking at the set for the thighs, and maybe (probably not) the set for the arms. I can't take long WALKS, because of arthritis in my knees, but I do work with free weights for curls and such for my arms. Floor exercises from long ago are helping my legs, but adding such a product couldn't hurt. My specialist ok'ed the belt for me to try, and I'm glad she did! I am not obese, but I am full figured. Not the same thing for those of you who are snickering. At the age of 14, I stood 5' 7" and my measurements were 38-26-38. I weighed 128 pounds. I wore a 34 DDD/F bra until I was about 25, then it went to 36 DDD/F. Within 6 months after the birth of my first child, I was back to the same measurements, but with a little extra "belly pooch" below my natural waistline. My proportions have remained roughly the same in ratio, with a general gaining of weight slowly over 30 years and a total of 4 children. I now wear a 38-40 DDD/F bra. I don't see gaining 6 inches around my ribs over that time as a tragedy, and I have the other measurements still in proportion. This belt, giving me the feel of a more solid core, has kept me doing the leg exercises that keep my calves sculpted (much to the surprise of my 18 year old daughter! They are cut!) and the will to continue light free weight exercises for my arms, despite the expected discomfort from the arm that has been through a shoulder surgery (it just kept slipping out of, and back into, socket, painlessly) and a radial nerve release. Anyone with a remote knowledge of anatomy should KNOW that MUSCLES tense, not fat. That was stated in an earlier review. BUT, what HAPPENS when these muscles flex? ENERGY is used by the body to allow this action. WHERE does this energy come from? NOT from the belt, which causes the contraction. The ENERGY comes from the BODY. How is excess energy stored in the body, waiting to be used up? AS ADIPOSE TISSUE, more commonly known as FAT. It is the same energy deposits that are used up during conventional exercise, people! Fat is fat is fat... Burn it up however you choose, if that is your goal. This belt will tone the muscles under the abdominal fat, and it WILL burn stored energy already in your body = FAT. IT IS SIMPLE SCIENCE, WHETHER THERE IS DOCUMENTED PROOF FOR THIS OR ANY OTHER PRODUCT OR ACTIVITY THAT REQUIRES MUSCLE FLEXION ANYWHERE IN YOUR BODY. Folks, you burn fat with every breath you take, even while sleeping. The key is finding a way to burn that fat (some use "calories") in the most efficient method for YOURSELF. I hope this triggers some memories of common sense, as far as exercise goes. Not every BODY needs, or can use, the same techniques that work for a DIFFERENT body.

I received the flex belt super excited to try it out because of all of ...
I received the flex belt super excited to try it out because of all of the great reviews I read. I read one review that said you wake up sore the next day and a few reviews that said to start off at 20 (because it was so intense) and work your way up. Here's my experience, after charging and putting the belt on, I set the intensity to 20 and couldn't feel ANYTHING. I felt no shock, no contracting of my muscles...nothing. It felt like nothing was happening so I kept pressing up until I could feel some type of contracting and feel as if it was doing something. The lucky number I finally felt something at? 95. It was insane to me how so many people had given a review that 20 was so intense only for me to have to start at 95. Anywho, I gave the belt a try anyway. I wore it 3 times a day for 30 minutes each session for the past 5 days. Not even one time have I woken up the next day and felt sore or felt like my muscles went thru a workout at all. I know it takes time to see results as far as inches and that kind of thing, but if it's actually supposed to be engaging your muscles and working them out then I should feel SOMETHING during or after workout the next day. Since wearing this belt I haven't had an experience that I can say makes me feel as though this belt is effective for me. I just don't feel as though it is actually doing anything for my stomach. However, I've given this product 3 stars because I'm not quite sure if it's ineffective or just ineffective FOR ME. I'm a new mom who had to endure a C-section so if you went thru a C-section, it may not work for you either.

Lower back problems - try all the flex products!
I have had a bad back for years. Tried everything - physical therapy, acupuncture, chiropractic, and finally surgery. Nothing worked long term. I noticed the best modality for me has been the tens unit my therapists have used on me. At least it felt great while doing and and I had lasting results. Of course, you can't just stop using it or your condition goes back to what it was and maybe worse. I knew the technology of the flex belt is pretty much the same as the tens unit. I have purchased all of their products ( Flex belt, flex min and the flex arm) The belt and the mini (butt thigh lifter) are the best for me. The belt is strengthening my core to the point where it allows me to work out harder when I do crunches and any other core type exercise - it has really helped me build up my ab muscles. I could have never gotten to the point I am now without it. As for the mini thigh lifter, it feels amazing on my back area - just like the tens unit at the therapist. I love that I can use it whenever I want and get the benefits from it immediately. It has been a lifesaver for me and I could not imagine spending the money on co-pays for the rest of my life, and worse limit myself to the amount of therapy my insurance company allows for the year. I would have to pay out of pocket to continue with the tens unit. Economically this made perfect sense to me. If you are looking for weight management - I feel this helps with that also. It was not my intention but I have lost inches on my stomach for sure -not so much on my thigh area as of yet but I am sure (for me) it is because that is more difficult to do. I had much less fat on my stomach area to begin with. I do feel that my legs are noticeable stronger - I do not have much trouble running up stairs and walking longer distances like before. Like I said. I have been throw the mill with my back problems and after my surgery - which resulted in a staph infection that left me laying in bed for 3 months. My muscles atrophied a bit and I had a hard time getting back into a routine that consisted of exercising. This has made the difference to get me back on the road to good health. I highly recommend for anyone with limited mobility such as myself, as well as anyone else who needs that extra push!

It works but it is not a magic pill
IT works in fact any electrical muscle stimulation (EMS) device will theoretically work and do what it is supposed to do, which is strengthen and tone the targeted muscle group on which you are using the device for. So let us get the nonsense of "will it work" or "It does not work" out of the way. It works full stop. It will make your abdominals stronger without a doubt. "But why do I not see abs like those on the tele or on Cristiano Ronaldo?" Well my dear it is because you have to much body fat. Let us take for example olympic class heavy lifters, they can lift tremendous amounts of weight it is quite sickening really, however most of these lifters not all look rather well huh how do I say, oh yes, Fat. I can assure you they are without a doubt stronger than most "fit" looking people their muscles are stronger too. The reason we do not see the muscle definition is because the muscle in covered by fat. Same with when you watch American football and you see the offensive or defensive line men. These men are incredibly strong stronger than me that is for sure yet they do not look like they are fit. Why? cuz they have body fat around the muscle. So if you buy this and expect to sit on your lazy arse eating crisps all day whilst having this thing on your belt, do not bother you are lying to yourself Slendertone are not lying to you, no you are lying to yourself. The solution is simple and it is old it is just not easy to do it takes dedication, try and eat a little bit more healthily and exercise run lift weights yes do it. Run for your heart and lift weights to build muscle because muscle, check this out burns calories for you when you are not even doing anything its so amazing I know. How I recommend you use this incredible product from Slendertone who are the most reputable company in commerical EMS products, is to use this device to cut down on your workout time. Instead of spending hours trying to do 1000 sit ups I use the belt whilst I am running whilst I am lifting weights it is not easy buy it will help enhance your results. So you can listen to all those tossers out there whom would swear to you that this is rubbish or you can listen to how your body works which is strenghtening muscle + cutting body fat = Results Thank you God bless, get the bleeding belt and into the gym Oh by the way Bruce Lee used EMS devices too and also exercised like a mad man its not new stuff.

説明書がありますが あまり詳しくないので どれくらいの強度で 平均はどれくらいで 筋肉をつけるためには どのくらいが適当なのか加減が、よく分かりません。 強度が0~150までは 幅がありすぎで まよいます。 ココよい数字とは どんなものでしょうか? 使っている人が言うには。あまり、強いと 下痢になるとか? 便秘の人には 良いですよね。 強度60で ためしましたが 60ですと べつに ザ、フレックスでなくてもよかったかな? スレンダーエボリューションでもよかったかも?!

偽物の可能性があるし、体に悪影響あるかも
使い始めて1週間経って使用中にエラーが起こりました。それだけでなくそのまますぐにスタートしてエラー中に溜まった電流が一気に流れてくるので体がスゴクびっくりします、正常だったときよりあきらかおかしいです。不良品です。 下手したら電流で発作を起こしそうで怖いです。 製品が来て箱の裏にAssembled in China と書いてあり中国で組み立てられたものみたいです。 本物は箱のそこに製品ナンバーを貼ったステッカーがあるみたいですがそれもありませんでした。 購入の際はよく考えたほうがいいかもしれません。
