I had to loosen it a little out of the box. I have not had a pieces popped out, which is always good. I think this is the least expensive cube at a great quality out there.

I haven't lubricated this yet, but this cube has done well for me. Since it hasn't been lubricated, it still has a bit of graininess to the turning texture, which I'm sure will work out with some lube. I've set my new unofficial PB with this, so it's definitely better than what I had before.

I lived it with weight 4 and Compound V and it is really smooth, overall great performance for a beginner to intermediate solver.

This cube is incredible! I used to use a Angstrom Wuque and have since switch to this cube. OOTB this cube is smooth and a bit sandy. Over all 5 stars.

I recommend getting this cube, because it has such a good price and seems to me to be a very good cube. It is however, my first magnetic 4x4, so I do not have as much experience to judge it from others.
The cube is very smooth, quiet, and has beautiful shades(mine is stickerless). Corner cutting is over 45, and reverse corner cutting is about half.
