Good small cube for OH and you can get your fingers around it really well.

Good for beginner oh solvers...

The 50mm Zhanchi is a great cube for OH solvers and collection purposes. It comes with dull stickers and are easily replaceable. I would also recommend setting up this cube to avoid hearing that awful spring noise. The mechanism is exactly the same as the Zhanchi. It is just at a bit smaller scale. Overall, I would recommend this!

I first got this cube for 3x3 OH solving. I think it is a little too small but 50 or 55mm would be good. The turning is very nice and smooth and cornercutting is average. This cube occasionally pops, but only when pushed to the limits. The shades are really good and don't chip. I would recommend this cube to people who want a small cube.

I bought this for OH, but it is not my main. The subpar reverse cornercutting accounts for frequent lockups. The cube also pops rather easily.

The cube was amazing out of the box and had smoothness and corner cutting straight away. After tensioning, lubing, and breaking in, this cube became amazing and an instant OH main. The torpedo pieces act amazingly well, preventing any annoying pops and corner-twists during your speedsolves.
