            The battery power has been strong and lasts beyond normal use. The only con is the string, though the auto feed is okay, the string perhaps could be either stronger or designed/textured to cut better and last longer.

            The battery lasted long enough for me to cut and trim two of my highest bushes without any issues or stagnation.
