Most product listings show five blades; a smaller number of descriptions mention six or seven anti-friction blades.
Product details list both manual (non-powered) handles and battery-powered handles that provide gentle micro-pulses.
Listings describe a blade refill as lasting up to 30 shaves — a figure that the listing notes is based on about three shaves per week.
Many listings specify "All Skin Types," while some product entries list "Normal" skin as the recommended type.
