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.
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.
