Straight out of the box it is gritty and locks up any time you try to move two adjacent layers simultaneously. Makes sense for an $8 cube.

This cube is cheap and can be turned remotely smoothly. But it locks and pops a lot which is frustrating. I would only recommend this to someone who is not yet sub 2:30 with 4x4. I was averaging 1:40 on 4x4 with this, and when I switched to the Yuxin Little Magic M I suddenly averaged 1:05 with little practice. For people trying to push sub 2 or even sub 1, I recommend the Yuxin Little Magic M or Meilong.

looking at this cube, i thought it would be horrible. ootb this puzzle was slow and had a dry sandy feel. After doing about 3 solves i decided to put in 4 drops of dnm 37. After that this puzzle is not fast and super smooth. I would give this 5 stars but the only problem is its catches a lot and is kinda loud, it also has very nice sticker shades.

The action is very smooth and the cube itself is extraordinary compared to off brands! Thank you GuanSu.

It is horrible. It does not corner cut at all, it locks up so much, and it is slow.

Just get the little magic or the qiyi ms

The YJ GuanSu out of the box is awful. The cube is very tight and sandy. I figured that it might be the residue left from the factory, so I disassembled it, wiped everything out, lubed the rings and tracks with Weight 5, and put some Candy Cane lube (I did it for the smell, you can use Silk or Mystic) into the outer layers. Then I broke it in with about 20 solves, and it is amazing. It retains the crunchy feeling that you get when you loosen it, but I don’t mind that. The cube is fast and corner cutting is great.

If you are planning on solving this even remotely fast you're in bad luck because this cube will pop with a TPS of at least 3-4. Don't buy this terrible product.

This abomination of a cube would pop a lot and feels like people dunk this garbage into sand. Unless you like a popping nightmare and a psychopath. Go ahead, buy this heap of crap.

I bought this and for a while it was my only 4x4 and when I went over o a friends house he had the V cube 4 and it turned better than this. I have had multiple pops on this cube. Dont buy it.

All THREE I ordered came crunchy, dry, and tight. After about 2 weeks of breaking in became comparable to my friends Moyu AoSu. It is no joke, the BEST BEGINNER cube and still my current main. It's good for anyone with slower more accurate turning speeds. (I average about a minute) ... (I'm not the greatest)
