Electric toothbrushes are available on the market now many. But in this Oral-B Professional Care, the price performance ratio is a stunner! A powerful Electroseparators toothbrush with 4 different attachments (brush, polisher, toothpicks and tongue cleaner) for 2 people ... plus a very long battery life. The price is fair and the nachzukaufenden parts (brush heads, etc.) are not much more expensive than a regular manual toothbrush. In any case, one should quietly forking out a few Euros in terms of dental care - a bad investment, it is not safe!
