Electric shavers
Electric shavers were a personal-care row inside small electronics. Two cutter designs cover almost the whole shelf: foil and rotary.
A foil shaver is a thin perforated screen with cutters moving behind it. The foil is fragile and it is a wear part. Running a shaver with a dented foil nicks skin and ruins the cutter under it. A rotary shaver uses round heads that flex over the face. The heads clog with hair and skin oil, and a rinse under the tap is allowed only on models marked washable. Water in a shaver that is not sealed kills the motor. The charging stand is brand-specific. A lamp that never shows full charge is often the nickel battery inside, which likes to be run down now and then, unlike later lithium packs.
