I bought the XXXL one, its excellent, feels really smooth on my mouse but most importantly it is insanely durable. This week I have been a bit clumsy, spilt a fizzy drink and just now coffee. I was worried it might get stained but nope, easily wiped that mess off. That's a big deal for me especially with larger desk mats. Really solid stitching and quality, definitely one of the best desk mats you could probably get.
A bit on the expensive side but honestly its worth the price for me at least, I can see this lasting a good 5+ years and its easily machine washable as well.
