I confess. I was taken in by an infomercial late at night. Fascinated by the ease of use, maneuverability and function. I've had this for three seasons and it doesn't disappoint. If you have a large yard, the weight is so light, I'd guess about 5 lbs. Easy start, easy to switch angle and the battery life is super. Changing the string is also a snap, literally. The replacement string just snaps in place. Can't say enough about this weed whacker. If you have a very small space, this is also perfect, because you can use it as a lawn mower. It maneuvers around lawn furniture too.
