listen. i'm a complete beginner to skewb. this cube arriving today was my very first experience holding and turning a skewb ever. i was hoping i'd like it, since it is hard to find video reviews online for this one. i have to say i'm extremely pleased with my purchase.
imagine the rs3m 2020, but as a skewb. that is what this cube delivers. the turning is smooth and quick, but not uncontrollable after getting used to the different way that it turns compared to a 3x3.
after adding lube and adjusting it to my liking, i am completely addicted to the turning feel of it. i learned beginners method quickly since you only need to know sledgehammer, and i'm just so pleased. this is a great product!
