I got this bundle as a gift for Christmas. The stackmat itself is great, I like how you have to hold the reset button for half a second to reset in order to prevent accidental resets. The mat is nice, and it doesn't slip around. I just wish it was a little thicker. The bag is nice as well, it fits both the mat and stackmat, and still gives some space for a few puzzles as well.

The timer is good, but if you already have a gen 4, stay with that, but I didn’t so I got this. The bag is pretty cool, and the mat fits well on a normal sized desk. I would recommend this over the bundle, because the other bundle seems to have a bigger mate

Great timer had no problems so far

Timer and mat work perfectly and the bag is perfect for transporting your gear!
