Hello, first of all, it is friendly to the side look. Then it is not heavy and the handle on the top center of gravity avoids wear through. The noise, almost nothing compared to my old Flymo and much less compared to thermal. Autonomy, I have some 100 m2 of real grass laid in roll and so fed up seeds that feed the ants. Summary: worth 5 stars, except the life that I can not judge, I'll be back order.
