So far they have been great. But...where I have them mounted...as low as I could...you can't really see behind you because of the rear fender! Still, I am very pleased...they have full adjustments...AND the fold in...and you can adjust how much force it takes to fold them in...spring loaded I think. Angle adjustment can be done at the mirror mount AND the mirror within the casing adjust as well.
I think I will add a small convex mirror to the center of the roof mount on the front roll bar. Flat spot there to stick a cheapy there.
