Bests & Worsts Reviews from Amazon

I bought this thinking, "it probably won't work but I'll give it a shot for 12 bucks" I have 3 big dogs and they were moving my little front entrance mat all over the place. I had one of those non-slide mats under it at one point and it didn't work at all. The rug really wasn't heavy enough. I've had these suckers for about two weeks. The rug has not moved AT ALL since I put them on. All my dogs do is run at the front door and bark at everything moving. Check out the pics.
