Found my razor on 3 and 180 degrees from the position I left it. Did my wife shave her pits at the sink or was there another culprit?! It was my 17 year old. "I didn't shave with it. It fascinated me," he says. I'm guessing it was set on 3 because he adjusted down and found it difficult to adjust back up. I let him know that he ought to open the doors before adjusting the setting.
