I bought for about $75 a pair of Rain-x "Silicone Advantage" wiper blades.......in 2017.
They're still working today despite being on a daily driven, stored outside GMC Sierra. I don't know *when* they'll need to be replaced again, but it sure doesn't look like any time soon.????
And they have been through at least 2 if not 3 ice storms and 103°F weather in every summer. The only damage is a knick in the top part of one where an ice scraper hit it. That's all.
