I bought mine at the beginning of last year. I also have a Black & Decker. The WORX is easy to reconfigure to different angles and the battery seems to not run quite as long as my black & Decker. As far as the edger aspect goes, it is great if you use a gas edger twice a season. I have St. Augustine and it is a very tough grass with a propensity for runners that will take over a sidewalk. If I edge every time I mow, the runners are still tender enough to be cut by the WORX. I like the line they have (it is the twisted kind) and the auto feed works well. Do buy the extra battery if you are irritated by having to stop mid flight because you have no more juice. I do not leave mine on the charger because it does shorten the life of battery.
