Great quality, they were easy to install and look like factory grade but seem more durable. No noise when wiping away the tears of mother nature. So yea, they resist rain and snow the tough kind from Maine. They work as they should and look great on my car. They haven't flung off yet so I say they're safe and you should buy them. Installed on a 2016 Subaru Crosstrek.

Works great

Great wipers for the price. I change my wiper blades every year after the winter thaw and these are my go to. They'll last a season no problem, just remember to clean the rubber with some alcohol wipes or cleaning solution to get the grime off. Wiper blades get beat up during winter so at this price I just replace them all.

Very nice wiper blades and the price was right. Read the directions first, as I did not and made more work for myself. 😆
