ShengShou Crazy 3x3

The ShengShou Crazy 3x3 is a pillowed 3x3 with rings on each face that do not turn with their respective faces. This leads to interesting situations that you would not normally see on a 3x3. 
This crazy 3x3 is built for speed. While performance isn't as good as standard 3x3s, it is well ahead of other "crazy" puzzles.
