I got a set of the magnums a few years ago and they vibrate around 4000 RPM but are pretty clear otherwise. The stock mirrors didn't vibrate at all but didn't give me the wide angle view I get with the magnums.

Worst of all, a lot of us become unpaid agents of whoever is controlling the agenda by enforcing the current dogma on the few rugged individualists who actually exist.
