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!

Absolutely fantastic! These suction cups and hooks are a game-changer, offering unparalleled strength and versatility that will revolutionize your camping experience. I must emphasize that they are so incredibly strong and versatile! They held our awning securely to our Minivan during a recent camping trip, even during some occasional windy conditions! Additionally, their impressive holding power also makes them ideal for hanging camping or fishing gear, adding a significant practical benefit that will elevate your outdoor adventure gear organization! Whether you're a car camping enthusiasts, a traveling game, concert or festival enthusiast, or just someone requiring reliable tie-down points for any other reason, these suction cups are an indispensable asset! They are an absolutely must-have for anyone needing reliable tie-down points! With the ability to withstand 150 pounds or more of force, they demonstrate an unwavering grip like a baby to your mashed potatoes, that will inspire trust that your gear will hold exceptionally strong! I mean, they are so strong, it would take Thor to pry them off! I have tried them on various other surfaces and their performance is consistently impressive! Additionally, the straps are made of high-end feeling nylon and the clips rival those of your higher end brands! If you're looking for some strong, reliable, yet affordable tie down points, look no further, because these babies are tough! I highly recommend them for their outstanding performance and value that will transform your experience!

Great suction and is very sticky!

Got these suction cups to put a shade on some plants in my backyard. Summer is really hard in Texas and some of my roses and other plants really suffer even when they're "sun resistant" plants, Texas is just too much. Well they are now relieved of the hot sun at noon and afternoon thanks to the shade. Suction cups worked just fine holding the big shade from the pergola to the side of the roof. Easy to use, great quality and just the perfect size. Since the shade fabric is dark grey they look just fine, I liked the style. Reasonable price. I am happy with my purchase.

These work very well. They suction quickly and easily and are held firmly in place. I used them to hang a tarp from the garage to the driveway to provide some shade.Its nice to be able to put the tarp up and down as needed. I just keep the suction cup hooks in place so its ready any time I need to put it up.My guests were impressed with the inginuity. Will definitley be buyingmore for other projects I have in mind. Great value for the money.

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.

Bought these to have a point to secure a tarp off my car when camping. If there’s any wind gusts (5mph+) these will struggle to stay in place and often times disconnect and go flying into my car. As others have mentioned, these come with adhesive on them initially but if you are someone who needs to disconnect and reconnect them while moving between campsites, this adhesive quickly disappears and you are stuck with very poor suction. These are great for non-windy conditions but if you have any gusts of wind and the tarp somewhat blows around, these quickly disconnect and go flying everywhere (often into your car). I’ve tried cleaning the spot I’m connecting to as well as cleaning the suction cups before connection but they still seem to struggle to keep connection in wind. It’s more of a headache to use these as I find myself always having to reconnect them multiple times as they come flying off. Wouldn’t recommend for campers looking for them to stay on for a few days. These might be good if you want them to stay in place for a few hours in non-windy conditions.
