I have had this product for just a week. It was purchased to put under a rolling chair for my sewing machine cabinet. So far it is working just fine. It seems very substantial and for the light use I make of it it should last a long time. .
When it became apparent I'd be working at home for a while I realized I needed something to protect our new carpet in my home office space. This mat works as expected although the chair leaves divots in it. But the carpet underneath is fine after being vacuumed.
It arrived flat which is a plus. But it is too thin and even on my low pile carpet my chair has created indentations and the casters get stuck in them. Spend more and get something you will be happy with.
