I got the purple one. It’s a nice thickness and works great with the Gan timer. When I first got this timer, I saw two holes at the bottom on either side.*
I like how they considered the size and shape of the mat according to how they should ACTUALLY be. It’s a rectangle, and when you place the timer on, the space you have for the cube to land on is a nice square (unfortunately this is my problem with the scs mini mats, them being a little too small).
*Beware of this when you order the mat but the holes are there so you can attach the Gan timer.
