This was my first 5x5 but its performance is amazing. If it pops it is not the Easiest to put back together but I have had it for 2 and a half months and it has only had one major pop. The other problem is the case. Do not use it. Grit gets into it really easily and scratches up the 5x5. But over all it is a amazing cube which I would recommend over the MGC.
