Electronic Muscle Stimulators
There are two legitimate electronic ab belts in the US. Slendertone and Contour. The former has been around for a few years and Contour has been available for about two years. I have tried both. They actually do flex and relax the muscles in your abs. Neither of them claim to be the answer to your fitness goals. From what I have seen is they simply offer a better way to work the abs, especially if a person is prone to injuring their back. If you have not tried either of these, I suggest you do before making unproven comments like they dehydrate you as that is not true. Neither of these shock you. They won't harm you. It's worth a try.
