1” on top, 3/4” sides and 1/2” on the neck bottom. “Feel” and experience. Don’t need a mirror. About 7-8 minutes in the bathtub. Another couple of minutes for the wife to clean up the neckline. Done in 15 minutes including clean-up.

Versus going to the barber then coming home to take a shower. At least a one and half hour waste of time.

Plus I do this 20 times a year….about $400 for a barber.

Plus I have short hair which I like. Versus waiting a month or so to go to the barber.

(Then there is the manscaping.)

Been doing this for maybe 10-12 years and never looked back.

Most important…….bought good equipment to get consistent results. Only need to buy it once.
