Review on FDA Cleared Rechargeable Wireless EMS Abs Stimulator Muscle Toner – The Ultimate Electronic Power Abs Trainer for Men, Women, Bodybuilders | Abdominal, Arm, and Leg Training by Jeremy Mondragon

At first, this product was great. Shipped quickly, everything was intact, worked as advertised. I used it for two and a half weeks without issue.That said. I was using the ab stimulator one morning on a lower setting (I believe level 2 or 3), and the device malfunctioned and shocked me VERY hard. enough for me to tear it off my stomach immediately and yell. This was not the normal escalation of pulse strength. It HURT. I have not used it since, but I have examined the device, and everything seems to look fine. Nothing is visibly broken, the electrodes are still in good shape, and when I'm not using the device, it is kept in the box on a shelf where no one can knock it off, drop it, spill stuff on it, or otherwise damage it.When this happened, the electrodes were stuck firmly to my skin, there was no gap, I wasn't doing anything that could possibly cause it to misfire (no electronics were around me, I wasn't on the phone, I wasn't in contact with any water or anything). I was sitting in a wooden chair talking to my fiance. I believe this was caused by something not working right with the device.
