I bought three of these mats - one for our back door that has a concrete stoop and the other two for our doors that go out to a composite deck. The one on the concrete is awesome. It catches quite a bit of debris from boots and shoes and is easy to hose off for cleaning. I can’t use the other two on the composite decking because they slide on it badly. I have order an indooroutdoor accent rug to lay under one mat to see if that helps with the slipping and will update when I get it.
