For most of my life I have used small scissors to trim my nose hair and hair clippers without a blade guard for my ear hair. Every once in a while I would manage to accidentally cut myself. So, after four years of using Skull Shaver products to shave my head, I decided to try their little attachment here. I have only used it once (I only got it two weeks ago), but it is worth the money. It is safer to use than my aforementioned methods; works just as well at trimming; it's a little quicker, too.
