I got sick of using $15 blade replacements as they only lasted 4 months if that, and I wanted to get rid of the metal supports for the blade, probably why the blades weren't lasting that long. Well I found a solution....If anybody is about to change their wiper blades with winter coming up. I highly recommend the Bosch Aerotwin wiper blades http://www.bosch.com.au/content/language1/html/5534.htm. I paid $65 incl postage on ebay, might be able to find cheaper. Have other people used these?
