Inlifiny 4pcs Non Slip Mat and Rug Grippers Anti Skid Carpet Rug Hallway Runner Gripper(Black)

When I opened up the package I was pretty doubtful these would work because they're quite stiff and the prongs are not more than 1/8" in length maybe less, in fact in some areas the prongs were broken leaving stubs half that length. But it was worth a shot at my entry way. I have a pair of matching sisal rugs that I use end to end instead of a runner in front of a shoe storage / seating area. This is all on top of med-low pile, worn-out apartment-grade carpeting. So it's no surprise with carpet underneath and tons of traffic coming and going and stopping to put on and take off shoes that those rugs are never where there supposed to be, let alone next to each other simulating a runner.The challenges:I was doubtful that the prongs would be long enough to hold in anything longer than outdoor carpet,I was doubtful the adhesive would hold on a material that sheds as much as sisaland I was doubtful that the stiffness of the grippers wouldn't make them pull up from the carpet every time someone stepped near it instead of directly on it.How I applied them:I figured I had 2 options I could place them so they were aligned with the direction feet would be walking across them, or I could turn them so they were laying across that path. I decided given the challenges I mentioned and the descriptions of problems in the negative reviews that I needed to get these strips as close to where we were walking as possible. So I placed them like footsteps down the rugs. they're not in the middle, or along the edge they split the difference the same way feet would be spaced apart.-I put the adhesive on the gripper first, and rubbed it on really firmly, I could actually see the air bubbles being pressed out which let me know the adhesive was nice and strong.-I left the protective sheet on the other side of the tape for a minute while I flipped the grippers over and eyeballed my placement.-Then I pulled the backer off and pressed them onto the rug.-Then I carefully (cuz those spikes are still pretty sharp) I ran a finger down the length of them between each row of spikes to really push as much of the sticky into that rug as possible.-Last I flipped the rugs over and carefully positioned them.. I say carefully because I was nervous about accidentally pulling of the freshly applied spikes.Then I left for work knowing Hubs wouldn't be back for several hours so the adhesive would have some time to set.Coming home was the test - I'd see if Hubs coming in the door, removing shoes and walking on had disturbed the rugs at all, at very least they're normally an inch apart after that.. HaZaah! the rugs hadn't moved at all, and I got down on the floor to check. I was amazed. Even better after 72 hours including several errands and even bringing in groceries the rugs are still in place. The attached pics are from today. You can see a tiny gap has developed, interestingly I was able to tug the edge of the rug back into place without actually moving the rug so that gap may be more because sisal rugs don't hold their shape well, than because of any migration of the spikes. I'm still impressed. They might not turn out to be a cure, but they're DEFINITELY managing the symptoms. Even if I have to slightly adjust the rugs once a week, before they were NEVER in the right place so I'd call that pretty close to a miracle.I think the key really is placing them along the direction of the walking path as much as possible (aligned with footsteps like "II" instead of across them like a T or X shape). It really seemed like that cured the problems other people were mentioning. If you have a rug that people would be walking on in lots of directions like a large central area rug, Place them like a firework out from the center of the rug. Forget placing them only along the edges or at corners. And I'd think you'd probably need at least one gripper for every 2-3 square feet of rug you're trying to hold down.

These work for my needs, but your mileage may vary. One thing I do NOT recommend is following the directions. According to the manufacturer, you're supposed to place the spike side into the bottom of the rug, and the adhesive on your carpet. Excuse me? That's a fantastic way to ruin your carpet with absolutely no effect on the rug slipping. Most rugs bottoms are too coarse for those little plastic spike nubs to have any grip at all, and they'd likely break off in the attempt (mine came with several nubs already broken.) Do it the common sense way- adhere the spikes to the underside of the rug, and place the spike side into the pile of your carpet. If you get the adhesive to stick to your rug securely, and you have enough nap in your carpet, these grippers do help. I used to have to pull my rug back into place several times daily, now I only need a minor adjustment every few weeks. Another reviewer's suggestion was also helpful: position the spikes where people will walk. It will reinforce the pressure into the carpet.

I'm not one to take the time to write a review, but this product is literally garbage. Not only will it not hold your rug on your carpet, but it will basically ruin the carpet under the strips. You're supposed to place adhesive tape on the carpet and then stick the spike strip on top of it. After having them installed for less than an hour, I realized they weren't worth it since the rug was slipping all over. I went to remove the spike strips and adhesive but the tape pretty much just disintegrated into the carpet, leaving a nasty residue that will likely damage the carpet in the long run.Seriously, complete garbage. If I had a time machine and could go back in time for literally any reason, I would go back a couple days and tell myself not to waste my time, money, or carpet.

Bought a million things to keep my rug in place! This was the only thing that actually worked. I have a Persian rug on carpet floor and got all the gorilla tape and etc and none of them worked. This actually holds it in place. I’m buying more though because 4 isn’t enough for a large rug. But it’s a great price and product i’d recommend trying it if you’re using your rug on carpet flooring

I bought them to stop my dog's Waterboy from sliding around on the cargo carpet of the CRV. With a strong 2 sided tape, these bad boys work wonders. Sharp enough to annoy your fingers, these things seem intent on stopping any creeping or sliding that may occur......

These worked for about 9 months before the gripper started moving around on the rug itself. The adhesive doesn't hold these into place very well. I've had to remove them all together because they starting sticking out from under the rug, and just looked tacky. Will be trying something different to hold my rugs into place.

Doesn't work well with short pile carpet. Still my rug moves around, not as much prior to the grippers, but stillnot what i expected.

Didnt hold my hall runner in place. When it would slip we would step on the sharp teeth. It could have been my rug but it didn't work for me.
