Shaving, trimming or styling: the Remington Durablade MB010 does it all. So you get 1 device in the house where you create different styles. If you would like to alternate a smooth skin with a small stubbly beard, then use one of the 3 combs. These stubble combs trim on lengths of 1, 2 or 4 millimeters. Shaving or trimming you do just under the shower, this electric razor is 100% watertight. The useful life is 40 minutes; enough for multiple shaves. When the battery is empty, charge it to the supplied USB charging cable. And there are no additional costs, the blades stay sharp for 5 years.
