I've never solved Rubik's Cube, but I've never seriously tried. One reason is that most of the cubes I've used are poorly made. They lock up when I try rotating a section, which is frustrating.

And it's very smooth to turn, because of the rounded off interior corners. I also got the MoYu YJ Lingpo 2 x 2 x 2 Speed Cube, which I'm going to try to tackle first.
