Save your $$ get double take mirrors.
I was fully refunded
Why, would you NOT have the fastners with torque or allen head fastners. Could never keep mirrors in place. After I went and switched out fastners with a allen head fastner and was able to torque down mirrors. Now mirrors are accetable.
The mirrors are nice to have to keep track of traffic behind me while out on the roads. The mirror are a little awkward in adjusting them, and one doesn't get quite tight enough to keep from moving.
