An upgrade from the regular Yusu and GuanSu , where they combined the best of these cubes. YJ Yusu R is a smooth cube with half bright stickers. It measures 62 mm in diameter and weighs 140g . It performs right out of the box, but even better after break-in . Yusu has a good balance between quality and performance.
