Nice and cheap.
Great product, have used many times and I am definately starting to see a difference (although I am doing regular sit ups along side.) Causes an increase in Ab definition, For all those craving a summer six pack, buy this now. Build quality left me wanting. Half of the pad stopped working after 6 months. But for a fiver I wasn't expecting much more. I have had 2 in the last year and the second is still going strong. There is a small flaw in the product that it from time to time turns itself off. Doesn't really make a difference though as it can be turned back on quite eastily.
