It is a pain doing slice rotation with this puzzle cause the mechanical part is awful except sometimes when the layer are perfectly aligned. It is definitely not suitable for solves because of its low quality. I don't recommend it!

Only buy this cube if you just want to display it!. It is quite harddd to turn but on the good side, it looks kind of nice. J2018

Update on my last review:
I finally got around to learning Square 1 and try and solve this beast, I couldn't even finish my solve (middle layer parity) that the cube broke apart. Really, I don't know if any Super Square 1 is solid, but this one definitely isn't. Don't purchase this unless you plan on never turning it nor displaying it (so yeah, if you plan on buying it to throw in the garbage it will work as intended).

On the visual part, the stickers are poorly applied and the layers align badly.

On the mechanical part, this cube turns really poorly and is a pain to use as the barrel inside the four layers seems to turn on his own accord whether it's gripping the outer layers or not at the time.

I would really not recommend this puzzle, however it's still turning and seems solid so I choose to rate it 2 stars.
