Hey I have a FastAbs Deluxe, and I love it, put it on my abs and obliques during cardio... use it on arms and lower back too after training them hevaily.. What kind do you have Crimson? You can buy replacement pads real cheap on ebay. I bought the FastAbs Deluxe for $40, comes with 2 smaller pads for arms and legs, and one big that one supports two programmers. I think they are pretty good for strength, and to tighten and harden muscles, I am also an amateur boxer and tend to be able to take a punch to the abdominal region better.. Only trouble I would have is it burning my skin making it all red, I've had mine for about 3 weeks now and I have noticed tighter, stronger abs... not a huge difference with the arms though, but my lower back is a lot stronger too. And only good use of it is for strength knowing it only works isometric.. so fat loss and muscle building is almost out of the question.. although have heard of it taking off a few mm's of fat , maybe good before precomp? Well i hope this can help some skeptics out.... Peace
