Years ago when Oskar first presented the prototype I thought it was the coolest most brilliant idea in Twisty Puzzles in a long time but never thought it could be mass produced. I was dumb-founded when it was released, and got it within the month of its release. This puzzle is easy but definitely harder than a gear cube so it is an enjoyable solving experience, and it is fun just to turn it and watch it turn, it truly is a spectacle and something to show to other people. The puzzle turns so well that it will often turn by itself, the thing just loves to turn, but in a good way. As long as you keep a good grip on it you shouldnt lose control of it.
