The red series of Einhell is highly recommended. The red series is loud Eihell a professional series. Since I myself am craftsman I can speak from experience that the tools of Bosch (Blue Series), Metabo, DeWalt & Fetool are already stable. However, the red series of Einhell stands after the home improvement series of Bosch (green) in nothing. For what has sometimes to do a handyman to grinding, this machine is suitable TOP. The price is about other Home toolmakers not too shabby in comparison. In many home improvement magazines (z. B. Yourself, Even the man) can be seen in the photos of the individual processing steps of the tools Einhell Red. I think that has its basic ;-)
