i have the flat 270mm for tinted windows. it fits perfectly in between the visors so they can come down (i dont know if the 300 will allow both sun visors to come down). i got the one for tinted windows because it's brighter than the other ones for non tinted since it's harder to see through tinted windows and i plan in tinting my windows.

i didnt get convex because i dont want the image i'm seeing to be non proportional. but it's nice since you can see practically everything behind your head

 

not even, im seeing a ton for 9.99

placing order now...

 

my 300 non convex fits dead center and JUST clears the visors when down

 

I didn't even know they had one for tinted windows, that's perfect. Where did you get that one?

 

So whats the verdict? Convex or Flat ?

 

nice bump, lol.

i personally like the flat ones. my gf has a convex one in her car and every time i drive her car and look at that mirror I want to throw up.
