This was a replacement for a cheaper mat so we do not know how well it will hold up under a years use. The limited lifetime warranty was the controlling factor in our purchase.
If you need an inexpensive desk mat for your home office this is the one to get if you have low pile carpeting. I would not recommend it for a business office with heavy use.
I have always used a chair mat under our computer chair in our den. The chair will not roll easily on the carpet and when the old mat wore out I replaced it with this mat. It is really nice doesn't have those ouchy sharp cleats on that old ones had and the chair moves easily on it. It's great and a good value.
We purchased 2 of these mats. After reading the reviews I was concerned that they would not lay flat. When they arrived I flattend them out one ontop of another and then placed heavy 5 gal. jugs of water on the corners and center for 2 days. After that they were completely flat and we haven't had any problems with them.
