Really cool cube! This is my first speed 2x2. Using it and the algorithms included in the instruction pamphlet I was able to drop my time down to less than 10 seconds in a couple of days. A few days more and I hit 1.9 seconds as my PB!
My only concern with the (stickerless) cube was that the tiles seemed to be coming off when I first got it. After pushing them back in they’ve been fine every since. Highly recommended!
