CONBOLA Suction 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)

These suction cup hooks are exactly what I needed to hold a reflective shade over my camper shell windows. The suction cup itself is made of a high-quality, Alien Tape-like material that creates an incredibly strong bond. I used them to hold a taut bungee cord across the width of the window, and they performed flawlessly. Even in the direct Arizona sun with temperatures exceeding 105 degrees, these hooks held firm without failing. I am very impressed with their performance and will definitely be buying more. Review Highlights: * **Durability:** Withstood extreme 105°F+ Arizona heat without losing suction. * **Material Quality:** The cup uses a superior, sticky material similar to Alien Tape. * **Functionality:** Perfect for securing bungee cords and lightweight window coverings. * **Value:** High-performing product that warrants repeat purchases.

Fantastic! Stayed stuck for 2 weeks and still going strong! The suction is VERY strong, it takes Hercules to pry them off, and that's a good thing. These are NOT wimpy things that will come loose and fall of in a few minutes like all the others I've tried. I stuck them on the inside of my SUV's windows in the cargo area and attached bungee hooks and cargo netting pulling on them with a LOT of weight, 150 pounds of stuff pulling against them. It was asking a lot of them to hold that much weight & pressure with the straps pulling tightly on a long 2000+ mile week-long road trip. But they held perfectly! What a nice surprise they never came off even once, not loose at all, those babies were stuck and not going anywhere. I have not tried them on other surfaces but for clean glass in your car even with temp changes it holds incredibly strong! UPDATE: They are STILL stuck tight after ONE MONTH! I finally took them off and it was hard to pry them off, as in very hard, but that makes them good. One thing you will want to do is make sure you keep the plastic caps they come with covering the suction cups, as you will need to put them back on over the cups when you take them off whatever they were stuck to. This is because the inside of the cups are sticky with an adhesive type surface and without the covers they would get covered with stuff immediately and that would surely hurt their sticking next time you use them. So keep those caps, they are attached but if you cut them off like I did, make sure you keep them!

We use them to hold our swimming pool ropes for creating lanes. They do a great job, but do not last very long..

The suction cups are so sticky that they stuck to my car roof even without engaging the suction cups (which works as expected). The built-in suction cup covers are a nice touch for keeping them clean when not in use… time will tell if they work but I’m hopeful.

I've been camping, road-tripping, and setting up temporary rigs for over a decade, from weekend state park trips to month-long overlanding runs, and I've tried just about every "heavy-duty" suction hook on the market. Most of them either fail in heat, lose grip overnight, or can't handle real tension. These CONBOLA Suction Cups Hooks (Heavy Duty Camper Accessories / Car Camping Essentials) genuinely surprised me. First thing I noticed: the seal. A lot of suction cups claim to be heavy-duty, but they rely on a flimsy lip that curls after a few uses. These actually create a tight vacuum when you press and lock them in. I mounted two on the sides of my SUV to secure a tarp for shade during a hot Texas afternoon, and they held up to 90+ degree heat and steady wind. No slipping. No slow sagging. No midnight collapse. Pro tip from experience: clean the surface first. I wiped the paint down with alcohol before mounting. That extra 30 seconds makes the difference between "works okay" and "rock solid."

There's no doubt these will stay put when attached to an appropriate surface. I used them to help affix a screened-in tent to the front of my camper and they worked great. My complaint is they rely heavily on the adherence/stickiness of the application surface as compared to actual suction. They'll stay put, but getting them off without damaging the sticky face is a chore. I'll be interesting to see how well they stick after multiple cycles of putting them on and taking them off.

You never quite know how good a suction you will get. Quite surprised, a great product. I use this on my lawn tractor trailer to use for tie downs, and on the boat to for whatever. Mostly for the trash bag, and I can move the bag around. once in place delightfully strong. NO DRILLING into the fiberglass.

You know that feeling when you open a package and start to look at the product you received and regret the shoddiness of how cheap the product is? That's how these are. They aren't really "suction cups" either! The suction cup material is more of an adhesive than suction. I cleaned the surface and put the cup on, but before I even pulled the suction part down, I went to reposition the hook, which I couldn't easily. The material is sticky as can be. Pulling up on the cup to create suction just doesn't really do anything, either. How would it create much suction when the cup itself is just a sticky goopy thing adhered to the surface? The carabiner clips are probably going to be the first thing to break, or the screw will corrode in a few days. Either way, this purchase is a sure way to feel remorse after receiving it. Find something else.

Got a pair and one does not stick at all! Will return immediately

These work really well

Very helpful to all my projects that requires suction cup hooks to stick on metal walls, and rails in my balcony. The products are well made, sturdy, and reusable, very strong. I am using them to set up my privacy screen getting ready for winter to prevent the snow from falling on my balcony. I bought more of them. I recommend them to all customers out there. I give it 5 +++++ stars.

Perfect for my purpose
