I have only had the mat for a month or so but I like it really well. It is not as huge as my last mat so it's easier to move when I vaccum and the cost was much much lower than my huge mat which was much heavier and much bulkier to move when I used the sweeper. It seems to be holding up well even though I am at the computer several hours each day.
Not really much better than the cheaper one. With time it crumbles cracks disintegrates. Chemical cleaners of any kind make it turn brittle and fall apart.
