It came to loose for me out of the Box, but that was fixed pretty easy. Very smooth layers and a good amount of size makes this cube excellent.

Amazing puzzle

Excellent puzzle! The tensions on mine came too loose though. Once tensioned, it will pop/lockup less, and it also takes some getting used to to avoid those lockups. But you practice on it while, you'll see its potential.

Also, the puzzle is quite a bit lighter than MoYu's 13x13 and is about a centimeter smaller which fits much better in the hands. Just be careful cutting because the mechanism still hasn't been perfected for cutting willy nilly during speedsolves.

needed adjustment as popped three times during first solve, one screw head stripped while adjusting... extra screws included so ok. after adjustment much much better. nice presentation box.
