This puzzle is a great step up from both the Clover Cube and the Curvy Copter. The turning's very smooth, but unfortunately, the center pieces pop out somewhat often. As long as you align it well, the issue can be avoided, but it's frustrating to stop a solve and have to pick up a piece. Tightening the cube slightly might address the issue.

Works great, although it should be noted that it's slightly larger than other 2x2x2 Mastermorphixes

Excelente modificación del 2x2. sus colores son perfectos y no presenta bloqueos.
