The cube outer layers were pretty nice, little unstable, but not a bad 4x4 especially for beginners.

This cube was sandy and not too fast but not too slow right out of the box. My very first solve on it I got a PB!!! It was very fast after doing solves but the tensions were very loose. Despite being loose, the cube seems very stable. Does catch a bit but I like the rough turning verses most of the more smooth Yuxin and Moyu offerings.

I cannot decide between this and my YuXin Blue to be my main. This one is a lot faster and more consistent between all the layers, but it has a bit f a stability issue, which is not something you want on :z4. I love it and it is definitely worth the price!

I started out with a YJ guansu which was ok. When I received this I was amazed. It never locks up, corner cutting is great and everything else about this puzzle is amazing. It is fast and crispy which I enjoy. Definitely pick this up

It's crazy that this 4x4 is only $8. I've tried the Weisu, Aosu, Shengshou, and Guansu before and this tops all of them. It came slightly loose out of the box, but after tensioning it's hard to find anything that could be improved. It has a nice slightly sandy feel, and can corner cut about a piece and a half, and half a piece reverse. It required pretty much no set up. I literally put a tiny line of weight 1/traxxas 10k, and it was perfect. I highly recommend this cube to anyone!

I've had the kung fu for a little bit more than a week. It's a good cube for the money . The more I use it the smoother it gets.

it is a awesome cube it is very smooth and sometimes pops out

i dont have this cube but i saw a unboxing of it. it has a buttery smooth feel out of the box. it also pops a lot.

For the price, it's really good featuring a smooth turning. It does however not have great cornercutting and locks up quite a bit, and stickers peel easily so I'd recommend the stickerless.
Alright for a $9 4x4

This cube is nice
