If I used a blade, my facial hair would only take a few hours to grow longer than the shave produced by an electric razor, and then I wouldn't be able or willing to shave again because it's such a time-consuming nuisance.

With an electric razor, I need only a couple minutes to shave and can easily do it 2, 3, or 4 times a day.

Voila! I average a much, much closer shave over the length of the day.
