While I truly despised the stock Mickey-mouse ear mirrors I must say the Powermadd's are, IMHO, not a reasonable replacement.
For me, they are too small and don't give the best feedback.
Being that they are typically mounted right out at the end of the barkbuster they do give you some view past your elbows.
That being said, they are small, and the fisheye lens kind of view is just not adequate for my comfort.
I constantly look over my shoulder whenever possible.
I'll be replacing mine very shortly with something that offers a better compromise between the stock MM ears and the Powermadd.
I'm old though, and my vision is getting worse, so perhaps younger, stronger eyes can see better with the Powermadds.
I would NOT recommend them. Just my 2 cents.
