I really, really love this piece. It's effective; the size is perfect, and it stays in place on my ottoman! I was really worried about having to adjust it every five seconds, but it's pretty solid overall. 

I will say, though, make sure to wash it off with a damp cloth before use. I may have wiped off a coating of some sort, but I do believe the top of it was indeed dirty. Otherwise, this is a great product!
