Smooth speedcube

Rubik’s Cube, and whenever I used to try, I’d get discouraged because the cube would lock up when turning it. Then I discovered Chinese speed cubes. They are very smooth and a pleasure to use. I’m working on a 2 x 2 x 2 mini-cube ($7) instead of the usual 3 x 3 x 3. Still haven’t cracked it! — MF
