I wasn’t as excited about a cube release as this one. If you like the Tornado V3, you’ll most likely find this cube perfect. It does feel a little but more tactile but in my opinion it’s not much of a problem. And about the improvements, the settings are much more efficient. (The handle is thicker so it’s less likely to break, and the magnet adjustment system are on the corners). As well as the fixes they have made about the cube breaking. For the V3, there have been a lot of ways the cube can break. However the V4 have fixed all of those problems. If you want to upgrade from the V3 or want a new main, I’d highly recommend this cube.
