I bought this cube a long time ago and finally got the courage to scramble and solve it. I watched a very good tutorial. But it is almost impossible to solve it, not because it is too difficult, but because it just can't move properly. You get stuck in the middle of the (easy) algorhythm, and when you finally manage to move it you get lost and have to start again and again. it finally popped and got split in the middle and I can't put it back to work. I think it is dead. Very sad, because if it worked properly would be a very nice challenge. :-(
