The cordless trimmer is very easy to use. When I need to trim or edge, I place one of black and decker's proprietary batteries into the battery slot of the handle for the edger. When I'm ready to trim, I press the button and it works well. If I need to edge, I rotate the disc over the string so it trims at an angle. It works well and is easy to use.
