I am retired and had a full beard until recently. I was diagnosed with severe sleep apnea that requires wearing a silicone mask over my nose and mouth while sleeping every night. In order to use the mask I had to shave my beard and now I must shave every night to get a comfortable and consistent seal to prevent air leaks around the mask. The Norelco PT730 is perfect for a quick, non-irritating dry shave at bedtime. Cleanup is fast and easy with hot tap water. I haven't used an electric razor in forty years. They have improved tremendously! If you are unfamiliar with sleep apnea, Google it.
