I love my Milenco Aero mirrors but if you can get milenco
mirrors £10 or more cheaper

I have the aero version but i always use it pointed (aero) end in towards the car as that way i get a better fuller view of whats coming up behind

Just a friendly tip to those using clamp on mirrors, if like me you worry about marking your car when clamping them onto your mirrors, get an old cycle inner tube (700c or racing bike is best size imho) cut it into tubular sections about 3/4 inch (i've used metric for all you old people ) then place a piece of ghe inner tube onto both the upper and lower section of the clamp I made about 30 out of 1 tube and keep them in my aero 2 mirror bag.

I'm 60 before someone has sense of humour failure

Gosh I thought you would be older somehow.

I will be tomorrow

I bought one of those Milenco Aero mirrors today it says on the box "fits any modern car"

They obviously never tried to fit one on a Vauxhall Insignia

Taking it back tomorrow
