I use one like this. Works well on nose and in ears. Won't get it razor close so for the outside of my ear lobe, I use my regular shaver.
Man, getting old has hair growing everywhere but where I want it!
This is exactly what I use at home. Protruding nose hairs drive my wife crazy; she can’t stand them.
When I’m driving and I notice them I just yank them out, usually after making eye contact with another motorist. People tend to give me more room that way.
