Additional Details ------------------------------ Product description: This Mat and Timer combo is the only equipment endorsed by the WCA for competition. Compatible with all brands and styles of speed cubes.

The new Speed Stacks G5 Timer features include:

1) Two operation modes: 2-Pad (for speed cubing) and 4-Pad (for stacking). Just hold the RESET button for 5 seconds to switch modes.

2) RESET and POWER buttons have a new reinforced design that won’t wear through with extended use.

3) Hold-feature on RESET and POWER buttons prevents lost times when a timer is slammed. To RESET or POWER on/off, hold the button for 1/2 a second.

4) TD cord plugs in underneath the timer so it’s out of the way and doesn’t accidently get unplugged.

5) A new snap-in G5 button system eliminates timers getting knocked off the mat inadvertently.
