🪞 Clear Double-Sided Suction Cups Review

They work very well IF you stick them to certain materials. (non-textured plastic, metal, etc.) I was hoping to use these to attach waterproof lights to the sides or bottom of my pool, but they don't stick to fine-textured vinyl.

I was trying to use these suction cups to attach some underwater LED lights to the wall of an above ground pool. I tested with another suction cup whether the suction cups would also work under water and the test worked. These suction cups have a smaller body and didn't fit me.

It's ok, but the grip depends a lot on the surface. They work very well on glass but not so well on plastic. I've tried using these to mount a toll tag on the windshield but they didn't last long. I ended up gluing one side to the transponder and leaving the other side attached to the glass.
