My husband bought this one day after his old one died.  It matched the drill set brand and they use the same batteries so all of them are interchangeable.  He doesn't have to worry about mixing gas and oil or using extension cords or cranking it 10 times to start it.  Its head is flips to be an edger, but we haven't figure that out yet.  When you are weed eating it auto lets out more string.  He can cut 1/4 of an acre before the battery is dead.
