The DaYan TengYun M 2x2 is a smooth, 50mm 2x2 cube that is one of the quietest puzzles in the market. It has a unique design and feels that sets it apart from other modern 2x2 cubes. This is definitely the best release from DaYan in recent times. The magnets applied in this 2x2 are tough which balances the control force of the hand and helps the cube turn quicker. The static breaking makes the speed cube rotation process as quiet as possible.
