i have a Tornado v3 and love the responsiveness plus magnets to confidently turn and know the cube will follow your commands. this V4 doesn’t have the same level of definition. it has slowed me down as i need to be careful how i turn the cube. i’m not a fast cuber and there are people who get amazing (to me) times with this cube so bear that in mind. this cube is on a par with a midrange Gan smart cube.
