Query: They are the best, but they still wear out

This wipers do everything they claim to do, as long as you follow the directions included...to the "t". But don't expect them to last forever, they still wear out eventually, like everything else. But they will last for generally a longer time, especially if you don't have a terribly dirty windshield.Remember to start with a perfectly clean, dry windshield before applying the special silicone solution...you really do get the best results!
