The turning of this cube is not that good and I guess that's because of its complexity. Turning as 2x2x2 is good but for all outer layers seem to lock up most of the time. For your dollars ? I don't think it's worth it but for your complete collection YES. Try it's on BIG SALE, let's say under US$25 mark. I've been playing with this cube for the last six weeks and there's not much luck with turning improvement. I did use a bit of lubricant which helps little. If you have money, try it yourself. It's still fun cube to solve after all.

Probablement, un des plus intéressant à résoudre !!!
