The driver side 28" blade in the new frameless style is hit or miss at a lot of the stores around me. I found the 'Trico Tech Beam Blades' online (both 28" & 21" ) and they work excellent. They just came out in late 2009 and what's nice is they have a lower, slightly off-set attachment mounting that allows the wiper arms to sit slightly lower. They’re beefy as hell and look sleek with the lower mounts. Wipe clean and quietly without chatter. Came with removal and replacement instructions - easy install. They fit the Mercedes-Benz GL Class nicely. Very nice replacement windshield wiper blades! Picked them up online.
