I have shot them extensively and hunted with one as well. I used to work for what was Howards largest dealer in the country, Lemme's Archery in Albany, NY.

The bow serves a very specialized purpose. It's for killing critters at 30 yards and closer. It is not as forgiving as a full length bow, but plenty forgiving for the average shooter to kill deer at 30 yards and closer. The size/weight benefits are a big advantage in a lot of hunting specific situations. It's really the perfect bow for hunting with out of a ground blind. One of the guys I used to work with shot one for a 3D season just for giggles and to show it off for a bit, and won every single event he registered in (senior class). I'd love to have another one and may someday. If you guys search you will see a very detailed review I put up years ago on the Liberty 1.

Edit - For those afraid of hitting your arm on this bow, it literally is impossible. The bow uses an X style shoot through cable system. You literally cannot hit your arm with the string, the cables protect your arm and won't allow the string to get closer than about 1" from your arm.
