I never bought a magnetic cube until recently. Just this last month, I bought four. This puzzle is the best 3x3 I've ever had. Gan air was my main for quite a while, but this one is a Gan, magnetic and stickerless. I prefer stickerless so I don't have to worry about chipping stickers with my fingernails. It's also 54mm which seems to make my one-handed a little easier.
Here is what this cube can do for you: You can cube longer with less hand fatigue. That means you can drill your algorithms and do more solves each day than you could on your old Rubik's brand. The faces turn with very little effort and the magnets are fairly strong which helps a face stop where it should. Great job Gan!
