This is my favorite 4x4. The size is perfect and I hope this becomes the norm. The 3x3 stage is much easier to control on this cube. It is not super fast out of the box, but breaks in nicely. I did have to tighten the tensions a bit because I had an internal piece pop out on me, and almost pop out multiple other times.

Best 4x4 IMO. Amazing dry feel. Slow out of box, but it seems to improve with every solve. After a few hundred solves it is a great speed. Corner cutting is reasonable. The smaller size makes 3x3 stage very nice
