REDCAMP Heavy Duty Suction Cup Anchor with Securing Hook Tie Down, Extra Strong Camping Tarp Accessory for Car RV Trunk Window Glass, 2 Pieces/4 Pieces

We used these suction cups to hold luggage bags down on the top of our van roof for a trip over 4,000 miles. You do need a clean surface to attach them to. One of the suction cups didn't want to stick for the first couple times, but we really cleaned the area it was to adhere to and cleaned the suction cup (after the failed attempts) and it worked great. Through wind, rain, ice and snow these kept our bags on the roof with no sliding. I definitely recommend these.

When I bought this product I was worried about the suction, that isn’t a problem at all till it’s cold out and you want to remove them. Any other time of the year the work fine I’d just keep the backing on them when you store them when you’re not using them bc they stick to everything, but like I said in the colder months they seem to freeze to whatever they are on if they aren’t in a climate controlled environment and they are a pain to get off, but eventually they disconnect.

These "suction cups" have an extremely sticky suction cup surface ... and, I'm not sure if its the suction or the stickiness that works (or both). One of the suction cups got dirty and stopped sticking/sucking to the roof of the car. The other one works perfectly. I used these suction cups to help mount a rear hatch car/van tent to my Caravan during a 2-week road trip. Every morning, one of the suction cups fell off and/or came loose. I may switch to large magnets for future outings.

Put these on outer wall of my smooth sided travel trailer to rig a sun shade over the wall exhaust panels for fridge. (Absorption fridge struggles in high heat with sun beating on fridge wall all day) This one place we go, my fridge exhaust panels, which are black, are in full sunlight all afternoon in deep south heat. I was able to put these near top of wall, and use the clips on them to hold up a skinny tarp I found on Amazon. The bottom of tarp was angled out and fastened to ground using a couple drill-in auger style stakes a a couple bungee cords. The suction cups were great, and did not budge despite windy coastal conditions and hot sun. No problem removing after 2 weeks in place, just flipped lever and gently started peeling them away starting at edge. No damage to RV wall surface. Back in little storage bag they came with (nice they came in little bag!) ready for next trip.

July 2021. First impressions review I would call these suction cups, light to medium duty. The bottom of the 'cup' is sticky. With that stickiness, plus the suction force, it looked like it stuck very strongly to different parts of my car. From vertical side panels to horizontal roof and hood. It held my weight well as I pulled on it and leaned away from it. I have a similar type of sticky suction cup inside my car holding a phone holder on an arm. Eventually, they do unstick. I think mostly due to heat on the window. Almost the whole assembly is made of plastic. I think the weak links on it will be the hook at the end of the nylon strap. It rotates on an axis that is all plastic and I think it will give way eventually. And the nylon strap holds onto the cup through a very thin metal pin that is held up by two vertical pieces of plastic that in turn is held in place by a round knob screw. As you tighten that knob, it flexes the plastic together, which likely will weaken. Or if the knob loosens by accident, it will release the pin holding the strap in place... Basically its a bad and weak design in my opinion. Also the bottom of the cup has a very small tab you can use to unstick the cup. The problem is that tab is so small its very hard to unstick. It requires a lot of force and patience. But the job will get done. I have a feeling those tiny tabs will break off one day. A bigger tab would be much better. And they do not come with any lid to cover the sticky bottoms. So when not being used they can get dirt stock to them, making them not as reliable next use. I cut some plastic coated cardboard and use it as a protector for the sticky bottoms. I bought these suction cups to add additional tie points to my car to hang a tarp from them, over the side of the car. Once I do that and spend time outdoors with that rig, I will update this review with how well or bad these suction cups performed. But on an initial test, they seemed to work quite well for this purpose.

This product surprised me as it works so good that is a bit tough to remove! I bought four of them to hold up a screen for movie night at the campground, and I could have easily only used two since I can hold the screen very tight. The only surprise was that the rubber surface is coated with a sticky substance that worried me at first since I thought that it might remained on the surface (i.e. like glue), but that did not happen… you have to pull quite hard and steady to remove it from the surface, but as far as I can tell, it leaves no residue… so mission accomplished!

I used these to hold a basket in place inside a bathtub in a trailer. The baskets do not hang, just needed these to hold the baskets near the wall so the contents don't roll around the tub while driving. These were placed on a clean, dry, stainless steel bathtub wall with the clips holding the baskets that sit on the floor. The baskets are small, about 3 inches by 8 inches and the contents were not heavy. I had 2 suction cups per basket. These worked great for about 2.5 months never removing them. One day two of them came unstuck (not removed purposefully) and will not stick back, now another week later and the other 2 have come off and will not stick back. Turns out these are not suction cups but stickers and once they are no longer sticky, they won't work at all. Just a waste.

I bought these to attach an awning to my SUV. They are super strong and I am very happy with them.

I purchased these to replace two suctions cups on my window shelf for my cats. They adhere really well and don't want to come off even when you want them to as they have a sticky layer as well. I am happy with my purchase and my window shelf has not fallen off of the window since I got these. If I ever have need for more suction cups I will purchase these.

MUy Buenos pero les falta algo de adherencia

I bought the suction cups to attach a camping tarp to my vehicle. They did not stick at all, the slightest of pressure and they cam off. The design of the suction cup does not seem to be right and they appear to be relying on the stickiness of the cup rather than a suction action.

Finally had the chance to try these and they were great. Used them to secure our pop up canopy to the side of our RV. Stayed suck for the week and easy to remove when we were packing up
