It comes with two batteries for longer tasks and is notably quiet, avoiding the gas smell. The lawnmower features a safety auto-shutoff, while the weed eater has a convenient tilting angle and auto-release string. However, the battery lasts 20-30 minutes and takes 8 hours to charge. It struggles with tall grass and has a small, delicate grass catcher, with durability concerns noted for the trimmer.
