This is a seriously good puzzle. I can't compare it to another Fisher cube, but I can say I'm happy with this one and I don't feel compelled to try another brand. It feels solid, the stickers are perfect and it turns very well. Solving it was fun because of the shape shifting, especially as the middle row centres can visually rotate too, which adds another aspect to the solve if you think of it like a basic 3x3 cube. It also has a last layer edge flip parity, and if you end the solve with a U-Perm it will flip a middle centre again, which makes it look impossible to solve as you have only one flipped piece. Great stuff Tony Fisher and QiYi. I totally recommend Kewbz fastest delivery too. Quality service every time.
