Amazing

Somehow kept everything faily clean while staying clean itself. It does not absorb moisture. Sand does not stick, but rolls / blows right off. The thing is durable. Did fine with our chair legs digging into it and our dogs nails before they learned to keep off.
It packs up teeny and super light. I thought it might be hard stuffing back in the bag (which is attached to itself so you'll never lose it), but that was not the case. Went in just about as easily as taking it out.
The corner pockets allow you to weigh it down with sand though it also allows for stakes. On a windy day, sand pockets are appreciated keeping the wind from billowing underneath if you don't have a lot of stuff on top.
Honestly can't think of any downside to this thing or what may be improved. Wish I'd had this sooner.
