I hate the stupid display hanging notches on the mat! I wish they had just made reinforced holes in the design and left out the notches. Call me OCD! Other than that it is a great mat!
It breaks down after a year or so because of my deep pile home office carpet. But I don't know that a more expensive one would do any better on this surface. So I stick with cheap and know I'll have to replace in less than two years.
