Assuming it's the same kind of cube as these (http://cubeforyou.com/305_White-3x3x3-Cube.html - I have the smiley one), they're not very good. They turn very, very, well, to a degree that makes it almost too good at turning. However, they cannot cut corners to save their lives. Plus, they're relatively small, too, so it's disconcerting if you're used to any other kind of 3x3x3.
