To me a no gaurd buzz looks lazy like the person didnt want to take the extra few minutes to finish shaving.
What I didn't realize was that at a #1, the urge to finish would be so strong, so overwhelming.
The #1 was Tuesday, and that Friday morning, before the gym, I buzzed it with no guard, then shaved on returning home and showering. That was probably one of the most memorable moments I've had personally. The freedom, the liberation was a rush unlike any other feeling I've had resulting from a change in clothing or grooming. It was totally over the wall. I've been shaving almost everyday since then, and each day enjoying the feeling of my smooth scalp as a great start to the day. But that's just my experience. My bet is that you will have a similar feeling of liberation.
