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.
The mat is much too soft. The wheels on my chair make indentions in the mat and I can't roll my chair very easily. It also won't stay put on my carpet....keeps sliding around. I have to readjust every couple days.
