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)

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!

Stick, stream, and race—camping just leveled up.We took these sleek suction cups—rocking black fabric with orange stitching—on our camping trip to hold up our projector screen on the RV’s fiberglass. They stuck like pros, turning our rig into the ultimate outdoor theater.Thanks to their heavy-duty grip, we enjoyed flawless movie nights under the stars and epic Mario Kart 8 battles projected right on the RV side. No sag, no slip, just pure sticky power even when the wind picked up and the competition got fierce.Stylish, strong, and campfire-approved, these suction cups are the perfect sidekick for any outdoor adventure where entertainment’s a must.

Great suction and is very sticky!

These suction cup hooks come in a practical 8-piece set and are ideal for outdoor activities such as camping or camping trips. They are designed with a strong suction that adheres firmly to smooth surfaces such as metal or glass, offering excellent resistance even when moving. They include a safety hook that improves grip and prevents slipping. They are perfect for holding awnings, securing tarpaulins or hanging accessories in the car, boat or SUV. Easy to place and remove without tools or perforations. A versatile and durable accessory.

I was honestly surprised by how easy this tent was to set up! The suction cups hold really well to the car and stay put, even with a bit of wind. It gives a good amount of shade and is perfect for road trips, beach days, or quick camping stops. It’s lightweight, folds up nicely, and doesn’t take up too much space in the trunk.

These suction cups come with an adhesive on them combined with the suction ability on the lever. If you're not planning on taking them off they are probably great, however my use case was that I need to attach and detach them. They attached great, but were very difficult to remove without tools once they were in place. The adhesive seems like it will eventually wear out and the suction probably won't hold very tight once that happens.

These suction cup hooks are awesome! I used them on my SUV to hold up a tarp while camping, and they stayed put the whole time—even with some wind. Super easy to stick on and take off, and they don’t leave any marks. Love that it comes with 8, and the green color looks great outdoors. Definitely a must-have for any car camping setup!

5 stars! I'm obsessed with this suction cup hook! It's so easy to install and use - just stick it to a smooth surface and you're good to go. I've been using it in my bathroom to hang my towels and it's been a game-changer. No more cluttered countertops or towels on the floor. The suction cup is strong and hasn't fallen. Highly recommend!
