The Cube Timer will help you time your performances so that you can improve day by day. You can easily connect your timer to computers, phones, or any screen. The reset button is located at the opposite end of the screen, where it will not interfere with starting or stopping the timer. There are also two connectors for attaching the timer to speedcubing mats and speed stacks. The timer can store the time up to three times in its memory, which remains even after restarting the timer. Clear instructions and images are included on how the timer functions. The timer operates on AAA batteries, which are not included.
