Everyone has an opinion. Mine is that they are different, and add something to the car.
Also, when mounted/modified correctly, I think they have the potential to work better than other designs, especially for a car that will have a wing, as mine does.
The pics above don't flatter them, but in real life, I think they look pretty good. Clearly a custom mirror for the car, and not an aftermarket add-on. When I saw the prototypes I was unconvinced, but the actual mirrors, on an actual car, look good to me. And I think they are more functional (because of their mounting height) than lower-mounted ones.
As mentioned elsewhere, in black they tend to blend into the DLO anyway- at least in real life. I don't know what they'd look like in body color, but it would be interesting to see.
