Hi Chris , I to have a Mazda 6 with standard milenco extention mirrors , again to full extention to see around the caravan and guess what , yes I also get vibrations . After reading on many forums that these mirrors are vibration free I came to the conclusion that it may be the car mirrors causing this , so was thinking about renewing for the aero type , but after hearing your comments maybe not . I am going away soon so will try Milencos suggestion and post results . Unfortunately when last towing down narrow lanes the passenger side mirror came in contact with hedging shrubs and broke the glass , could milenco please tell me where I could purchase another and approx how much , standard milenco mirror flat ( not convex ) glass . Many thanks , regards --- STEVE .
