I only ever trust setup like the bar end one. I used to have those cheapo one that i can clip onto my handle, which doesn’t vibrate as it doesn’t have a long stick, but it hinder my grip. Then i upgrade(downgrade?) to handlebar one. The FOV is nice and it’s clearer, but the vibration nullify the gains, it make the vision worst as I can’t differentiate what type of vehicles are creeping toward me, or if any, and it’s worst at night, so i drop mirror altogether. Maybe i’ll get a bar end one and see if my hand would block the mirror or not.
