I have tested the saw at the weekend in these situations in detail. What can I say, really convincingly. Super-handed operation, clean, fast cuts. Garden owners what more do you want. The battery life I have not explicitly tested, but I have a number of branches and cut in a short pause, the battery on the terrace has loaded quickly. See also the other Renz ions. For commercial use, there are certainly other professional devices, which are equipped with a removable battery. There is a green Bosch device for home users. Or you can just buy two units if the need arises.
The "reverse sawhorse" for the one-handed interface works flawlessly. German engineering flat.
With a small Gütelschlinge the device could also fix the tool belt, you have to have to take two hands free without the machine. The saw blade can be changed without tools quickly.
