Ya and about the whole vibration thing is there anyway to limit or get rid of it

 

Double post

 

I had the Bosch and had some streaking still brand new. I switched to the Rain-X style ones but on the 08 F150 it streaks a bit and shakes at highway speeds and doesn't do **** when its raining at the same time. The Cobra has them as well and doesn't have problems...weird!

 

I have the Rain-X mid priced ones and have no problem whatever. The Bosch really messed up my windshield.
