I'm after user feedback and not the video presentations from the you've been had suppliers in this world. I've got one of these Bosch Li ion battery screwdrivers and it performs superbly tremendous torque for a battery driven device, so I wondered it their lawn mower performed as well.
the Amazon site does contain a lot of user rfeedback - scroll to the bottom of the page to read the reviews - twenty six rated it 5 star and seven 4 star and nothing less than that.
