MoYu have released a new series of Mirror Cubes, the Mirror Cube is a variation of the Cube where the pieces are differentiated by their respective heights instead of their colours, the entire cube is all the same colour. The standard colour for the Mirror Cube has previously been gold or silver and that is the case here for the premium ball core UV verion, however, they have gone with an unusual choice of green or blue for the cheaper versions. Both cubes I unboxed in this video turn very well and I feel that the ball core UV version is probably better than the Gan Mirror which is the main competition. I think this is the best option for those looking to solve Mirror Cubes fast.
