The $5 per pair convex stickies on the stock mirrors do the job just about as well, IMO. I put them on everything I drive.
I'd say more like $3.00. I took my last bike back to stock before trading it in, and couldn't stand not having my spot mirrors on the short ride to the dealer.
The last thing I wanna do is turn my head around while moving forward.


Buy the wedge shaped ones for best results. Lane changes are a no brainer with spot mirrors.
As stated above, I put them on everything I pilot.
Including the riding mower.
