I LOVE This Cube, but sometimes it gets some pretty brutal lockups and pops. I tightened it up, but I still got some lockups, but the pops stopped and I had to sacrifice some of the turning capabilities. I realized, WAIT! I CAN PUT LUBE IN THIS! That was all it needed out of the box. I doubt that you're still reading this, so I'm just going to type some random things right now so you can spend more and more time reading this, While wondering why your still here, reading a review on a 7x7 Rubik's cube from some YouTuber in Canada. But anyways, Great cube.
