The mower is just terrific and is reliable, neat and clean. No comparison to the equipment of other manufacturers. The slightly higher purchase price is absolutely justified and money well spent. The construction and assembly are indeed well described in the manual, but already put technical understanding properly. I had even kelien problems during installation and then have me robe to the Husqvarna local who made me the relocation and has adjusted and programmed the robotic mower ... that was money well spent and therefore I can only to buy before place rates as one but is there in good hands and will be supported with any problems. In addition, the Husqvarna dealer can storing the customer's name in the device. ATTENTION .. Mower should be serviced annually by the local dealer. The device is simply recommended and good!
