What you couldnt finish your shave in the dark? Just feel the contours of your face with one hand and use the straght with the other......
Well maybe not. The lights going out was probably a good thing. This way you only did your sideburns/cheeks to start with which is a good place to start learning.
As far as getting a super close shave, on a good day (I am still learning) I do just that. No need to clean up with anything else at all. Sometimes I do find the neck area a little stuborn
but even then its rare that I need to touch up with anything else. Guess I am stuborn too.
