You know surprisingly I cleaned my blades every wash and have not had to replace them on past 2 cars for for 3 years each. This was in the north east, with OEM wiper blades on my Dodge Chargers.
Otherwise I've use the Boch Icons and Rainx Lattitude and were loads better than than cheap ones. They offered a cleaner wipe, longer lasting, amazing in rain, snow and sleet. Worth the money over cheaper ones.
The Rainx Lattitude also seem to apply Rainx via the blades when they are new. I think my past newer cars have had factory silicone blades and hence the great performance?
I applied Mothers CMX to my current blades along with windshield and its doing great. Your market my vary. I think my current blades are silicone.
