Hi, My advice to you is dont waste your money. I bought one of these about 3 years ago and it is pure tourture lol. Apart from childbirth it has to be the second most painful thing ever!! It sends electric pulses through your body and even on the lowest setting it bloody hurts ouch!!!!! I cauld never wear mine long enough to see if it actually works. Suppose it depends how much you like pain!! lol (some are into it but not me)
