I bought the silver version for $42. The metallized silver is very cool looking, however, it was tight, catchy, and very scratchy/crunchy out of the box, especially the inner layers. After loosening it by four quarter-turns and applying lube, it feels much better. I recommend a thicker lube for the inner layers. I'd say it has good forward corner cutting, especially for a mirror blocks cube, but only a little reverse corner cutting. The magnets make it nice and stable, and the magnetic pull is stronger for the inner layers (making the 3x3 stage easier). I think this is a great magnetic 4x4 mirror cube!
