CONBOLASuction Cup Hooks Heavy Duty 4 Pieces Car Camping Essentials Upgraded Tie Down Suction Cup Camper Accessories with Securing Hook Strong Power for RV Boat Window Glass Camping Trap.(4 pcs)

Ok, these are hands down the most durable and strongest hook/clips I hav ever tried. You can use them practically anywhere and they won't damage whatever you stick them on. I love to use them when I travel. They're strong enough to keep my bags off the floor!

These are great for the first time you use them. They are very sticky and held my tarp rock solid off the side of my camper van. Someone said something about microsuction, but that is nonsense. They are 100% some kind of adhesive. If you drop one on the ground, rocks, sticks and dirt will stick to them and can not be simply brushed off. If you touch one edge of the cup to the surface of what you are sticking them to it will stick. I didn't even need to flip the lever because the adhesion was so strong. Only down side was after a lot of effort to get them off, they left some chunks of the adhesive gel behind on the side of my van. The residue left behind was only a couple rice sized pieces and came off quickly with a little goo gone. Just more proof that these are more adhesive then suction. With all that said I would totally buy them again. They held great, even with some wind. I have not tried to clean and reuse them yet, for the price and how little I use them I treat them as disposable.

I bought these clips to secure a door in my house that my pup likes to get into. I had two of these stuck onto clean glass. One the suction cups kept falling off despite going from the plastic film cover straight to the glass door. One thing I did NOT know (I could have read the product description better) is that these are STICKY! I'm fine with it, they stuck onto glass, but just note they are to be used as a sticky suction cup. Even being sticky, that one still fell down multiple times. (I will say the last time I put it back up, I used some major elbow grease when I stuck it on, and it hasn't come down just yet.)Over all - this is a good product, great for the price. I would recommend

These are pretty cool good build quality good functionality easy to use Easy installation and they're adjustable so you can make them longer and shorter to whatever it is you want to hold and they're a good price for a pack of four

Fantastic product! These heavy-duty suction cup hooks are incredibly sturdy and versatile. Perfect for camping, RVing, or boating. They stick well to glass, metal, and other smooth surfaces, and the securing hook is super strong. Highly recommend!

Sticks well when brand new. But once you reuse it again it's worthless because it doesn't stick anymore.

I purchased a cargo cover that came with lousy suction cups, so I ordered these heavy duty suction cups to use instead. Huge difference! These work great!

Should have guessed, but the suction strength is incredibly weak. Used it with a tarp with light wind on my F-150 while camping and they didn’t hold. I only needed two to hold the tarp (the others were attached to the shell) and none of them held. I would not recommend these and will return them.
