long battery life, do not make too much noise, for cons, I had to return my mower because the adjustment of the cutting height (on the same shoe) is not practical and not stable, it just hangs on 2 or 3 position, otherwise all the other so there was a little adjustment for precise play regular transport cut, probably a default in the shoe plastic design otherwise 10/10 for monitoring and amazon customer satisfaction, as usual, thank you amazon
