Works for my purposes!
I purchased these suction cup handles to use on vertical sliding windows that are almost out of reach when open fully. The handles stick nicely to the glass panes of my windows and allow me to easily pull the windows down without having to grab the metal frame which is difficult to do on my aluminum windows.<br /><br />I wasn't sure if these would serve the purpose so I ordered one and it worked and then I ordered a second one and it worked and ended up buying two more of these to use on all of my difficult to reach windows. So far no issues with any of them.
