The best of the rubik's cube for me. Already lubricated, slides perfectly. I hardly ever corner twist or lockup since I use it. The faces are bein stickerless (note that this cube, white is replaced by black, which is not worse because there are more the difference with the yellow. Note that it must be careful not to let it slip on soil type tar because it scratches easily (good if you are careful it should not happen). The cuting corner is really good. Each euro is justified (more it is cheaper that a Rubik's cube of the original brand ...). This is a safe value.
