That's a nose hair trimmer guys...I know...I know, but the older I get, the more I use this thing. I didn't know such a thing existed either...but they do...and you know what...they work !!! No batteries for this baby either. Rotate the bottom half of the shaft and it set the rotary action at the top part in action...sort of like a lawn mower or shreader...it gets the job done men...so I shall say no more.
