I never rotary cut when I can roll a die through the baby machine or use the electric one. They are both out on the work table for quick and easy cutting of projects.

Mats are a wearable item and need to be replaced just like rotary blades and needles The mats should be shifted when placing on the die to avoid repeat cut lines. I've never seen or heard of one that cracks or breaks. I keep some new ones in the bin. However, I still have original mats from my purchases in 2015 that I use.
Good luck with your decision.
