The YJ Speedcubing Timer is a timer specially designed for speed cubing! The nice thing is that the timer reset button is not on the front of the timer, which makes it impossible to reset the timer by accidentally dropping your cube! This timer also has the ability to save personal best times and display an average of 12 or an average of all saved solutions. The exterior of the timer is packaged in a smooth, soft silicone finish that looks and feels great! It has holes on the back for attaching to mats equipped with timer fixings, and can be connected to your computer via an auxiliary cable. (AAA batteries not included)
