I will start by saying I have never had a rug grip  pad before.. It arrived fairly quickly.  I did feel there was a slight smell to it.  The smell wasnt very strong... I unrolled the rug placed it on the floor and put my rug on top . My rug has not moved in 3 days . Im very happy with it. It was super easy  I did it by myself. It works perfectly... The quality of this material  that its made with is very strong.  I believe will hold up for years to come.. I  highly  recommend  this product. I dont know why I never got one before instead of my rug sliding  around all the time. Thanks Wayfair
