I bought one of these when Best Buy dropped the price to $19.99 so I am pretty satisfied with it for the price I paid. I could not imagine spending the original $150 price tag for it though. It is a cool novelty and a fun addition to my collection, but that's about where it ends. I do not seem to have as much trouble with accidental turns as I have read in many reviews. I also do not have a ton of difficulty performing U turns.
Anyone looking for speed solving would probably not be very interested in a TouchCube. It is NOT made for speed and you can only manipulate the cube from the top face. This means that to turn the bottom layer you have to turn the cube.
It looks cool, and you can play with it in the dark, but a regular 3x3x3 cube is so much better than this version.
