I have the Kolpin UTV rearview mirror. Works well, no issues with it. I wouldnt get the sideview mirrors though. Had them and didnt like them because they don't adjust enough. Ended up going with On the Rox's sideview mirrors.
Take a look on amazon.. I picked up one that is a bit convex. I can see the full backend of the roxor from the botom third of the windshield. As it is suction mounted, you can put is where it suits you.
