I got the blue mirrors, they're okay. I like the look and they do reduce glare. Only thing I don't like is that it's not very hydrophobic. When it's foggy outside it seems to collect moisture a bit more than the standard mirrors. I just have to turn on the heated mirrors and it'll go away but it's just not what I had expected.
Not a really good shot but you can kinda see the blue tinted mirror.
Thanks for the picture and feedback. My husband thinks the blue tint looks cool. After having auto-dimming side view mirrors in the past, I am just surprised it isn't offered on the Signature line but do on the Miata.
