I've seen listed on some cube stores a Ghost Hand 4x4x4 but I can't find review videos for it. Anyone have any idea how good or bad this cube is? Looking for a first time 4x4x4 cube I can thrash while practicing and learning how to solve a 4x4x4 so I need a good 4x4x4 that won't fall apart if I should mess up a move, or if it does fall apart, be easy to put together again.
