Review on Qmagic Heavy Duty Suction Hooks: Enhance Your Organization and Simplify Storage Effortlessly! by Michael Boyd

I bought these suction cups to attach a 15 pound Christmas wreath to the outside of a large front windshield. I live in Florida so the weather doesn't matter. The description says they can hold 12 to 20 pounds. When I first attached them to the window the suction was great and they stayed in place. Hours later, when I checked it out, the wreath's weight was pulling it to the bottom of the window, but the suction continued. I had to use both suction hooks plus 1 extra stick on the hook to keep it in place. When I removed the suction cups, one came loose easily when I pressed the button and the second had to be pushed and pulled several times to detach from the window. Pretty decent product just not as strong as advertised.
