12PCS 18mm/0.7" Furniture Desk Glass Transparent Anti-Collision Suction Cups Sucker Hanger Pads for Glass Plastic Without Hooks

I used these to hang lights on my window and they worked perfect. It's hit or miss with suction cups. And these are a hit. They suck onto easily the first time, without having to work hard to make them stick. The window I use these for endures a lot of temperature changes and the still remain adhered. Very dependable.

Too small. Won't stick. Not what I ordered. Not what I described. Not what they described meaning the seller. Poor value. Cheaply made. Absolute junk from China. I do not recommend.
