I received the mat and was very very disappointed. I was not like my old one. My old one was thicker and more sturdy. Yours was very flimsy and very hard for the chair to roll on. I am very displeased to say the least.
The chair mat is in place and functioning as it should on an area rug. It does not move around during use. I can't speak to durability yet since I've only had it in use for about 10 days. It seems well made and it is definitely crystal clear. Hope it stays that way.
This is a good mat and the price was right. But even on low plush carpeting it is a bit too soft. after sitting a while in one place the wheels tend to sink into the grooves making it harder to push away from the desk. I probably should have gotten a harder surfaced mat to place under my desk chair.
