Engineered tough to last. The Virtually Indestructible Foil Shaver 5100 comes with a Lifetime Limited Warranty for long lasting, dependable shaving. The 4 Blade Cutting System features a special trimmer that pre-trims longer hairs so the flexing foils can shave close. The rechargeable battery delivers up to 60 minutes of cordless use after just two hours of charging. You get two great styles from one shaver with the included stubble attachment. It snaps onto the shaver head and creates a stubble that will enhance your look. Plus, the Quiet Drive motor is engineered to vibrate less and be quieter for a comfortable shave.
