I started last year on an empty bike trail and have never used a mirror in my life (way back when I was a kid prior to last year.) Now that I'm on the roads with the new bike, I bought the recommended Take-a-Look eyeglass mirror and put it on my helmet visor. I really like it, except the time I was easing down a very narrow and steep sandy road and kept looking in the mirror to see when the car was going to catch and pass me. When I finally turned my head, I realized it was parked in front of a house and was never going to catch me, LOL.
