i dont know how much this thing costs, but it looks like it would be kinda fun and actually pretty good i think to work movement on. The guy doing the demo I dont think does justice for the things capable of being done on it. some of the things he did on it were very ugly, the knees for example, kneeing the bag is a good idea, but since his knees kinda sucked, i dont feel it did a good job of displaying what could be done, does that make sense? anyways yea, this thing looks kinda cool and fun, like the punching bag you had as a kid, but for adults.
googled the price, $527, definitely not worth it.
