Review on 3M SRA 4 Protection Anchor System by Inyong Dow

I recently bought a new 5' x 6' rug for my living room, but I didn't realize it didn't have a non-slip backing. After weeks of trying to stop him from moving across the hardwood floor while someone was using the ottoman or my cats were playing, I decided to give these rug holders a try. They work great! It was very easy to stick them on my carpet and floor and the carpet hasn't moved since. I wasn't sure I would need more than one pack due to the size of the rug, but one in each corner holds up well. I have adjusted the position of the mat since I attached it and the pieces "click" together with no problem. Haven't tried removing them from the floor yet, but they're the same as the command strips, so there shouldn't be any markings.
