The Remington Power Advanced has double blades and 2 center trimmers to quickly shave a light to medium-sized beard. Is your stubble rather stubborn? Turn on the turbo mode for a smooth shaving performance. The electric shaver is fully waterproof, so you can shave under the shower, which is more gentle on your skin. Thanks to a very powerful lithium ion battery, this shaver lasts for 120 minutes. This is considerably longer than most electric shavers in this price range.
