I bought one and it worked absolutely great for the 20 or so times (maximum) I used it on my similar front lawn for the first three years. When I took it out of its shed storage this spring of year four it did not work for more than a few seconds at a time. I called Greenworks customer service who told me "sorry..it can't be fixed...it is out of warranty.. buy a new one"). Since I had purchased an extra battery, the hedge trimmer, and the edger for the unit; they worked well when I used them so in essence I was essentially "married" to the Greenworks unit-so I bought their replacement unit. The newer replacement would not cut more than 100 square feet of lawn similar to your video. I an disgusted and will return it. Never again with Greenworks. It seems they have a reliability problem with some of their stuff .
