REDCAMP Heavy Duty Suction Cup Anchor with Securing Hook Tie Down, Removable Camping Tarp Accessory as Car Side Awning, 2 Pieces/4 Piecces/6 Piecces/8 Piecces

I got these for camping so that I could attach a tarp to my truck and let it extend over the tail end to keep weather out of the back of my truck/shell. They are larger than I expected. They came with a cleaning cloth so you can make sure to get a good grip with the suction cups AND they came in a smart little bag...I apparently didn't read all the fine print, so this for me was a happy bonus. The bag is like other tent-type bags with a draw string and a plastic clasp to keep it closed. Appears to be heavy duty, yet not extremely heavy (happy medium when camping and concerned about weight. These are actually pretty light weight, but probably nothing a hiker would want, just car camping type activities.

I use these to hold sun shade canopy on my camper. The surface has to be clean and smooth for them to work. Great suction when properly installed. Do Not drop in the dirt! I had to wash one off and air dry, very sticky suction surface area. I save the little round plastic covers that came on them and reuse to keep clean. You can use zip lock bags to keep them in also.

This is something that you should be using in different places for different projects, but the stick suction cup gets really dirty. Other than that I don't have any problems. Because there is a sticky substance it attracts dirt and the suction cup starts to get dusty and dirty with debris.

I bought these for a banner at work they are attached to a glass window. They fell off the 1st day probably user error. Since then they have not detached once. Held up in all weather conditions

Used these cups in conjunction with the Hasika Universal Awning because they were frequently bought together per Amazon. Good thing I did because they were better quality than the ones that came with awning. Plus, having extra suction cups come in handy during camping. We used some To support tarps overhead. Definitely worth having these at your disposal

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.

When I first got these, I was dawdling at an event and stuck one to a window to "see how it worked". That was dumb. The effing thing took Heman to get off! The good news is that it sticks like no-one's business. My original plan was to use these to anchor a rain fly to my covert camper van. I don't have rails or a roof rack so i have to be creative. Now that I see how bloody adhesive these are, I'm thinking I'll use them to mount a roof rack instead. I have ZERO doubt they'll hold just about anything at highway speed. UPDATE: I would classify these as semi-permanent and adhesive in nature, rather than "suction cup" as I've not encountered a situation where they simply un-mounted or came off when releasing the suction part. I've had these on my vehicle in all weather conditions and temps with no movement and under a lot of weight.

These are great for one time use. But once you take them off they lose the adhesive on the suction and rarely are they reusable. Be nice if the company sold stuff to put the adhesive back into the suction cup.

When they say they hold fast they are not kidding. On a smooth, clean surface and you could probably hang a bowling ball from it. Hard to remove which for me is exactly what I wanted.

Suction cup does not hold at all. feels cheaply made.
