I bought Bosch Icon wiper blades (jointless, remember spending over $45) and they were a piece. Never made contact with the whole windshield and already were leaving streaks in 6 months. I got Anco jointless and could notice immediately that they had full contact with the windshield and I have had them problem free for two winters and a year and a half. That's including a few trips to the mud. They work great and only cost I think $25 for the pair after a mail in rebate.
I really only care for the jointless blades, once you get snow in those they are pretty much worthless
