I am very fast at 2x2 (5-8 seconds), but I have a lot of cubes to compare it to and think I can offer a good opinion. It was fast and smooth out of the box, and felt like a cube that would be a bit too flexible without magnets, but had a great balance of flexibility and stability with magnets. It corner cuts almost anywhere on near-stock stock tensions (I evened them out a bit, as a couple of sides were uneven out of the box). It had a bit of spring noise, but that went away after lubing the core with weight 5. I lubed the pieces with weight 1, and it is fast, but still controllable. I haven't had any pops yet, which was my issue with the Kung Fu. It comes in sticker less and is more smooth and stable, which is why I choose it over my ChuWen (and a friends magnetic ChuWen that I tried). I had trouble deciding between this cube and my magnetic WeiPo, but am slightly leaning towards this cube for subjective reasons and its slightly better corner cutting.
