I bought this cheap key-chain cube by z-cube hoping it would replace the yuxin one that I have. While the yuxin works well, I was hoping this would be a replacement in black with stickers that would look better to carry around.

Unfortunately I would describe this product as nearly unusable. The mechanism of the cube is that of an original rubik's brand, with no modern updated for turning or anti popping. This is functionally the same as a rubik's brand key-chain from 10 years ago with significantly worse plastic.

The cube constantly catches making it impractical for solving, and the cube is rather structure unsound and could easily pop in your pocket, making it impractical to carry around. The plastic is cheap and fragile.

The only reason that I give this cube two stars is that it is aesthetically pleasing with nice shades and plastic color. If you are looking for a key-chain for solely visual purposes, you could tighten this up to avoid pops and display it nicely with your keys.

So it turns well and it's a fun item to have. The only bad thing about this is that the keychain gets in the way and is not detachable.

i love this cube it doesn't bulge out of your pocket and it is better then the other brand, easy to maneuver and no popping.

pros: size is great, and it turns well.
cons: no corner cutting or magnets, and dry ootb
a drop of mystic and one of silk, and it is ready to break wr.

Not too big, not too small, I don't expect much from a keychain cube. Though it looks nice. the keychain's life span was nonexistent, and the cube quickly became a cube with a ring piercing.

Within minutes of having the thing and trying a scramble, it was very stiff and sandy. After about 5 minutes of playing with it, the centers started popping out. This cube is too small, for me at least, and it also has pretty much no corner cutting, atrocious to solve.

The cube can barely turn sometimes and when it does some of the centres will come out. It does do its job of being a cube just to have in your pocket when you're bored though.

Within minutes of having the thing and trying a scramble, the chain itself fell out of the cube. After about 5 minutes of super gluing it back in, the centers started popping it out on it's out. This cube is too small, for me at least, and it also has pretty much no corner cutting, atrocious to solve, and very clicky and clunky.

The shades are pretty nice though, and it is really inexpensive for less than 4 dollars. Don't really buy it unless you're looking for a really cheap key chain cube.

I got this cube, hoping it would be a fun puzzle just to carry around and to show to people.
First of all, it is tiny! Its so much smaller than I thought it was! It turns amazingly, and has a similar feeling to a MF3RS from Moyu's Cubing Classroom series. The shades are great and I haven't had any problems with the colours.
