I have decided to buy a pair of Milenco Aero Mirrors as they seem to get good reviews, but do I go for flat glass or convex? What are the advantages / disadvantages?
Convex mirrors increase your field of view, but they do have the disadvantage of making objects seem further away than they really are, as Damian says. Therefore, I think it is a good compromise to use convex only on the passenger side where the mirror is far away and one can consequently do with a bigger field of view.
