This chair mat has worked well so far; I installed it just a week ago. The last one I had began cracking after about two year's use so I may feel difference about my rating unless this one last longer!
The mat is too soft flexible and the wheels of my office chair just get 'stuck' in the indentation it leaves. It won't move. The mat is just not hard enough
I paid a decent price for this chair mat and thought my chair wouldn't make divots in the mat. I was wrong. it is hard at times to roll my chair on my carpet and the mat moves which isn't supposed to. I am not too happy with this purchase. I gave it a month to review.
