This cube is excellent out of the box. I’ve played with tensions out of curiosity, but you can get solving straight away.
Corner cutting is really good for a cube in this price range (greater than 45 degrees, if you get the tensions right). It’s not a quiet cube, but it sounds satisfyingly clacky and solid for a cube this light. I’ve not had any pops, but I’m still only sub-1m30s so I can’t speak for faster solving.
For red-green colourblind people like me, the colour range is just okay. The yellow/orange/green/red mix is close, but not enough to affect my solving times.
If you want a good cheap cube and you’re okay with not having magnets, you would be perfectly happy with this cube. Service and delivery were brilliant.
