Despite light turning and speed it's not so good for me. It's doesn't auto align and it overshoots. Magnets are too weak so when turning it doesn't snap into position. When I hold it, it feels slippery and does not hold square shape, so easy to misaligne. Feels like was designed for small kid's hands. Compared to the GAN UV-coated cubes, this one lacks grip and stability. The UV coating on GAN cubes gives me much better control.
