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.

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.

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.

凄くお腹に効きます、時間を掛ければ堅い筋肉に成ります。 最初から高いレベルだとお腹を痛めるので少しずつレベルを上げれば良いです。

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?!

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。
