Review (5/5): So far, so good
I have been using the 6423LC shaver only a couple of weeks. When I began using it, I noticed that it made less noise than my old older Norelco corded shaver (3405LC ?). That concerned me because I wondered if the newer one would shave as well. It does! I had my older one for more than eight years, and it was still giving me good shaves until I discarded it. Simply replacing the circular cutters was another option, but for a few dollars more I decided to buy the current model. I do not shave in the shower nor find a line-cord problematical, and I do not see how a more expensive shaver could satisfy me more. What I do not know is if the newer model will serve as long as the older one and without even a cutter replacement in over eight years. Time will tell!
