So I got a Rubik's Ice Cube about 2 years ago and I used to play with it, learned how to solve it and all but it was always extremely hard to move. It would keep locking up and my wrists hurt so badly from solving it. About a day or 2 ago I picked up the cube again and it was SO hard to move. Any tips on getting another 2x2? Also, I ordered some Lubix so maybe that will help it. Thanks!
