🔧 Adjustable Transparent 4-5CM Clear Suction Tightening Review

Waste suction power. No ability to maintain weight. I tried using them to hold a small tarp with grommets. While they work great with grommets, they don't stick at all to the surface they're supposed to be glued to. Poor suction power. Don't waste your time like me.

I have a weir (skimmer door) that opens all the way when the pump isn't running and all the debris it collected goes back into the pool. Terrible design but if you attach one of these suction cups to the entry wall the weir will now rest against it and nothing will come out. To make it quieter, I put a 1 inch ID soft hose on the nut. Very durable - she lays in the pool for a month without letting go. And I'm very satisfied.

I thought this suction cup would be perfect for my needs. I needed a tool to attach an external sunshade to our car's windshield. There is a metal grommet on each end of the cap and the description sounds like I could use a nut to attach a suction cup through this grommet. THIS FITS PERFECTLY. BUT . The nut had to be tightened to increase the suction power. Tightening the nut tightens the center of the suction cup, the tighter the nut, the stronger the suction. BUT . The sleeve for some reason…
