Hamnor Heavy Duty Suction Cups with Hooks Upgraded Car Camping Tie Down Suction Cup Camping Tarp Accessory with Viscous Silicone Strong Power for Car Awning Boat Camping Trap(2 pcs)

Used these in a shower to stabilize a 3 shelf high teak unit. Sticks to the tile perfectly and is not affected by the water or steam. Great purchase.

My primary intended use is for an entry rain roof for my awningless travel trailer. It tested well in a heavy rain, in fact the suction cups are way better and hold secure to any smooth, clean surface I tried them on.For whatever it is worth, one pole on the entry was purposely shorter, so the rain would drain off safely.

Clever invention. They make putting up tarps and a mosquito tent much quicker and easier for one person. They come loose now and then, so I have to also tie tarp corners to the wheels. Not perfect and too expensive, but I wouldn't want to do without them.

I bought these to hold up a sun shade on the side of my aluminum horse trailer. They did an amazing job in temps 100+ Degrees for three full days with a stiff breeze. Exceeded my expectations

I used it to hang something on a window. Stayed on there for about a week and fell off. Used two to hold the same device (picture) onto the window and it fell off after a week. Strong for awhile, then fails over time.

The suction cups were covered in some thick adhesive. That's what was sticking and not the suction. I had to use a piece of wood to pry it off of my jet ski.

I order suction cups, not a glue covered disk that looks like a suction cup. I don’t want to have to clean this sticky mess off of my car.
