I had never owned a 7x7 before I bought this, and I wish I saved my money and bought the yjmgc, which I ended up doing, because this cube pops, a lot! I had lots of pieces fall out before I tightened it too much to turn without it popping again! In other words, there is no good spot for tensions, after a major pop, I didn't feel like learning how to put it back together, so now it is sitting in a gan pyriminx box because it is the only one that can hold all of the pieces. The magnets also are too week to even say that it is magnetic on the box.
