Has anyone tried the Ab Circle Pro

I don't have one, but be careful because a lot of those products look so much better on the TV! I bought the Ab Lounge and that thing is still just sitting in a corner. It supposedly doesn't hurt your neck like sit ups do, but after trying it out I didn't even feel the burn like with sit ups. And it still hurt my neck. Plus I am apparently too short to use it fully so I can't get it to extend all the way. Yet on TV it looked so cool and I just had to have one.
