AB Doer Twist Abdominal Excercise Machine

The product didn't have great instructions for putting it together although it did come with a DVD - the parts weren't numbered or anything so it was really hard to know which was which. Mine appeared to be missing a bolt as well, although I was instructed to "deconstruct" a bolt from the "rear part of the main frame" I couldn't find a bolt long enough for the place that needed a bolt. One handle grip, the foam was ripped upon opening the package, and the other the foam didn't reach all the way to the end, where it attached to the handlebar. I couldn't seem to stabilize the center piece, which was supposed to support the back, probably because of the missing bolt, so I never felt completely safe using it. For the price, it didn't seem as solidly constructed as one would expect. I'm currently searching for a replacement.
