This 4x4 is really good. Compared to the previous 4x4 I used (non-magnetic wuque) this is so much better.

Very crisp, fast turning, with good magnet strength. Inner layers turn just as nicely as the outers, and the smaller size helps during 3x3 stage.

I still prefer my aosu gts2m because it feels smoother than this puzzle, but that might be just because I've used it a lot. Maybe the aosu wrm will get nicer after I've used it for a while. Time will tell. I like the smaller size but it isn't much of a factor for me. It's fast and stable but it just feels slightly locky right now.

The cube was slow. When you loosened it, the middle layers rattled a lot.

I really liked this cube in store, it tried a bunch of the 4x4s before I came to a decision. It was one of the faster cubes I tried least but was also very stable. The middle layers have stronger magnets making m slices that much easier. The outers are weaker magnets and I'm able to do my turns faster. Its an upgrade from my previous 4x4 but worth the investment. Its smaller size works better with my turning style.
