Basically, I am very satisfied with the saw. It is very easy and can be a long time to work with one hand, without the arm abfällt.Nur with the battery life is lagging behind a little. The read me assessments gave more than 20 minutes of continuous power, with me there are a maximum of 10 minutes. And if I want to saw a few smaller branches from the tree, must first be charged both batteries. Otherwise, the time is lost by promotion and relegation.
