Although this was a little heavier than I thought it would be, I just trimmed two rows of trees with it, usings different angles of the cutter and lengths of the arm. It took a while to get used to having to hold on to more than one button to keep the power on, but I soon got the hang of it. The battery was fully charged out of the box within a couple of hours, and lasted for longer than 45 minutes. It also recharged again with a couple of hours. So far, so good!
