Quality and works

While we as a family have tried many different types of rug grippers. First so we dont slip but also the dogs seem to like to use them as sleds. Then there are the kid who seem to like to pick at them. I just had back surgery serious surgery and I was worried that the rug beside my bed would slip. I bought these a little skeptical but did and the work perfectly. Preformed a little experiment since I would not be able to get up if I fell and could possible do more damage. My Husband put these rug grippers down on our wood floor (of course he was worried about the wood floor) not about me falling LOL. Well he then took up the first one and the wood was still the same. He then moved it to the curling part of the rug and it worked with no residue on the floor and really stuck . Gave this A+ for product quality and total recommendation.
