The SpeedStacks Timer Bundle Edge GX is a new miniature timer and mat bundle from SpeedStacks that is specifically designed for speedcubers. With a small form factor, the GX Edge timer and mat can be set up just about anywhere.
The GX Edge timer does not use a reset button -- just place your hands on the timer and the timer will automatically reset and start your next solve at the same time.
Please remove the plastic strip in the battery compartment to begin using the timer. The on/off switch is a small button near the battery compartment. Uses 2 AAA batteries.
