Amazed, I only bought gas edgers before this.  I've owned 3 WeedEater 2-Cycle Gas Edgers Model Number: PE550 over the last, I don't 15 years, and went to by another (they're good units, won't go into reasons I replaced them) and couldn't fine them anywhere, figured they were discontinued, finally bought a $500 Mclane Mowers edger (big mistake, not recommended, post comment if interest) then out of desperation broke down and bought this electric edger which I was sure would be "toy", wow, so cool, so impressed, worth the minor hassle of a cord, HIGHLY RECOMMENDED!  : )  oh, our home is < acre.  great power with extension cord: (amazon) US Wire 63100 14/3 100-Foot SJTW Orange Medium Duty Extension Cord .
