The mat is alright. It came very tightly rolled up and was a bit of effort to lay it down so it wouldn't roll back up on itself. After 24 hours it is better but not completely flat, yet.
When first unwrapped, it had a very strong odder that smelled like old people. The smell seems to be going away, though. If doesn't, I'm returning it. I don't need that in my life. Most of my floor smelled the first night.
Overall the mat is hard and very glossy. We'll see on the longevity but it seems very pron to keeping indentations on it from heavy objects.
