This is an excellent product. It is totally waterproof, and yet is quite light and compact to store away. Drys out in no time when the rain clears as well. Look out for pooling, try to lay it over the furniture so that the excess water runs away down a slope. Forget the perfect square image in the brochure, the water pools and sags inwards very quickly so you have to create a way for the water to run off.
