My toning belt has been working for ages, ive had it about a 2 years and is still working fine when i wish to use it, im writing this review now as im about to purchase another for my other arm as ive started working out again, i think this product works great, but maybe i have just got lucky.
first few days it worked, no problemo. but on the fourth day it stopped working, i thought the battery ran so, i replaced it with the spare battery(comes with device) but still didn't work. and you cant predict what level it is on so your in for a surprise of a level 10 shock. Basically its rubbish
