- Small - Fits comfortably in your hand, all points in the nose and ears can be easily reached. - Softly - Cuts gently, but well, not "tweet" o tearing of hair. - I use a AA battery to generate too much "waste battery". That's no problem. - Cleaning with water, to a rotating ring is set to "cleaning". Thus, the water drain hole is opened and water is allowed to flow from the top of the shaving head. then I build the shaving head apart (a few steps without tools), dry all parts and give a droplet Scherkopf- oil the knife. Unfortunately, such an oil is not supplied, also is no battery case. If the device is now even somewhat durable I forgive even a sixth star.
