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. 😆

Took my friend forever to put it in his car but when he finally did- zoom zoom. He is back in the road delivering your purchase and food. Fit was tight but most are, affordable part.
