Non-Slip Rug Pads For RUG-ON-CARPET ANTI-SLIP. DESIGNED FOR USE ON MEDIUM PILE CARPET. 8 Pack. Intended To Limit Medium/Large Sized Rugs From Moving On Top Of CARPET. BRAND NEW DESIGN!

Well I purchased 8 of these because we have an over sized extremely large rug. They will adhere to the rug but because we have very tight short plush carpet the anchors will not grip. I suggest that they tell people that they will not anchor to short carpet. I almost wish they were like straight spikes like cleats to really dig in and hold. These have a sharp edge that curves back to maybe hang on long fiber covered carpets. My carpet still wrinkles up in middle.

Oh too bad. Just about to request a label to send these back. Have medium thick wall to wall carpeting the bedroom-dressing room area. These Grippers would not even hold a 2X4 runner. Installed them, according to directions which are clear, last evening hoping they would be the answer. By this morning this runner had crept over to the wall of our dressing room which has been the same problem we have had with other products. Certainly not worth the money. A great idea which needs to go back to the drawing board. Also once they are installed you feel as if you are walking across a stream on stepping stones. I suppose on very thick wall to wall( and I mean very thick) these might grip and hold but not on even our very expensive carpet.

OK. I love it so far. I just put them on a 11' x 8' rug. I needed to fluff up my carpet with a fork (because it is old) and then step on the pad. I then twisted to the right (as instructed) could not twist much, but it seemed like it was not going anywhere. I will see what happens on a day to day basis and find out if it works. I also bought carpet tape for an added advantage, but realized that I won't be able to pull up the rug to put that on, without messing the adhesive up, since you need to put the pad in the carpet first and then attach the rug The tape will be my back up plan. If I remember I will post again as soon as I know it is working or not working.The picture I attached looks uneven, but it is an inch away from the TV stand. I should know pretty quickly if it starts to move. :)

I have a medium pile, wall-to-wall carpeting and I need to anchor a 2×6 runner and a 4×6 area rug by the front door. I installed these anchors and they worked fine for the first day; but on the morning of day 2, the area rug had moved itself out position and the runner was completely free from the carpet.The 'sticky' side that attaches to the rug holds fairly well - they are still clinging to the rugs firmly. However, once they are stuck to the rug there is no way to "reinstall" them by twisting them into the carpet.Unfortunately, the teeth that anchor the rug to the carpet just do not hold. I installed them according to the directions - I even vacuumed thoroughly and tried the 'fluff' the carpet as much as possible to allow for a better grip, to no avail. They seemed family secure when installing - I even tugged up slightly to ensure a secure fit and the anchor stayed put and pulled the carpet up from the floor. But, as I mentioned before, they only held the rugs in place for a day.I would not recommend purchasing these anchors unless you have an EXTEREMELY high pile carpet, and even then I would be cautious.This product is a great idea, it just needs a lot of improvements before it can be used for its purpose.

We have very thick and fairly high pile carpet. Want to have a protective 3'x4' carpet over the new carpet so bought 8 of these. Nope won't hold at all. The need to have longer teeth to bite further into the high pile carpet.

They didn't work on my short pile carpet but i bet it would with deep pile carpet.So, if you order it, just make sure that your carpet is deep pile as outlined in the instructions.

I have a 6x8" area rug that "moves" all the time. It sits on a medium pile carpet. I have tried a rug pad, double-sided rug tape, and this product. I tried multiple times to get the non-slip rug pads to lodge into the carpet without success. I'm sorry it didn't work.

Does not work. Followed the directions. The pad did not adhere to the carpet .Attempted many times to push the round disc onto carpet but did not latch.
