I don't like those 1 peice wiper blades. Perhaps they've worked great where you live, but for me, they were junk. Lifted off the glass in turbulent conditions, would get salt/mud/debris stuck between the blade and the glass ans smear like crazy.
I've stuck with the classic metal wipers for both summer and winter, with great success. The best way for people that want the reflex type wiper blades like the ones you got, is to use washer fluid WITHOUT teflon. I say this, because a lot of people make the mistake of buying Teflon coated or tippe blades AND teflon based washer fluid. This is a bad idea, as the teflon in each will counteract the other, almost like there is grease on your windsheild, and make them useless.
Let us know though how those ones you got work out after having them for a while...I don't recall hearing of those before...
