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!

This absolutely does NOT work your AB muscles
I have scoliosis and a lot of back pain. This means a lot of AB exercises will end up causing some back pain no matter how careful I am. So, I was REALLY hoping this thing would work and help me tone up my ABs muscles without back pain. Sadly, it does not. It is basically a non-medical grade TENS unit. I have 2 small TENS units for muscle pain and this belt feels about the same as those small TENS units. It just vibrates the skin and upper layer of flesh (fat). It does NOT cause the muscles to contract like they show in the ads. Those ads are ABSOLUTELY FALSE. I have cranked this thing up as high as I could stand it ..... to the mid 90s settings. The vibration is REALLY strong at that setting.... so much so that it actually hurts my skin/flesh, but it has NEVER caused my muscles to contract. My chiropractor had a TENS unit that did cause my muscles to contract so I assume that this belt is a not medical grade TENS unit, and does not travel far enough into the skin to reach the muscles. Simply vibrating your skin or fat WILL NOT tone your AB muscles underneath. I frequently turn the belt around and put the pads on my back to vibrate my back muscles, as it sometimes helps with the back pain. I would return this belt but my other portable TENS unit won't charge, so I may use this thing for back pain.

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。
