Didn’t work for me. Cleaned and lubed rubber gaskets, let dry. Installed window plates, worked the next day. Just tried them after two weeks, tried 3 windows, made openers hard to turn while they were pushing on windows, did not pop them, they went to open position on locks which was hard to do to get pass the push part. Then had to use suction cup to open them, so I could then close them, since once they slid past the plate you had to open them to be able to close and lock them. Now stuck with them on windows, should have stuck with suction cup method, now more difficult to open
