Calidad: Very disapointing factory. The machine work really hard, I spoke with the sales person and the answer was to use both joysticks at the same time. Thing that for drilling or trying to excavate verticaly it is imposible. so at the end I ended with a 8.000 euros after all the costs , of junk. here I leave a video ot how it works, so no one can say that it is not true.
