QiYi Valk 4 M (Strong)
The Valk 4 M is a solid 4x4 in the iconic Valk line. It is compact at only 60mm across, making it more comfortable to hold and turn. Turning each layer slowly, the cube has a comfortable, stable and smooth feel. When turning faster, there is a pleasant, slight hint of crunchiness. Corner cutting on this cube is flexible and on par with top 4x4s.
This version has stronger magnets.
