With so many wipers available on the market today it is tough to decide which one is most efficient.
The best one I have found is the PIAA Silicone wiper. The rubber blade is enhanced with silicone, which gets transferred to the windshield every time the wipers are used creating a super slick invisible coating which allows rain water to bead into small droplets and slide off with normal wiping. The silicone coating also eliminates chatter and squeaking which I found very common with other wipers.
Tire Rack carries a full line of PIAA wipers from 12-inch to 24-inch sizes to fit most of the vehicles on the road today.
