The QiYi Speedcube Timer is a great accessory that every cube-solver should have. First of all, you can get your cube-solving and time measuring to the next level. You do not have to use your old-school stopwatch anymore, and it helps you break records while getting fair and accurate results. Moreover, it gives you the right cube-solving atmosphere like it is during the competitions using it with the Speedcubing Mat.
