I think I've still got the Gilette sensor I got when they sent me one when I was 16 (no 30--yes, I fell into the man's trap). Have picked up a couple others over the years so I could keep at GF's house or put in a travel bag. A few years ago, I picked up a couple of electric shavers for a total of $13 when my store put some on clearance for 90% off. Still haven't opened the 2nd. But I only use those when I have light stubble. Thick stuff requires a blade in the shower. Less mess and less razor burn and ingrown hairs.
