According to reviewers, the Black & Decker NHT518 is the best battery-powered model. Although a few owners are dissatisfied with the battery life, which seems to diminish over time, David Beaulieu, About.com's guide to landscaping, didn't experience this problem over a three-week period. Most owners are pleased with this cordless hedge trimmer's power and say it's easy to use. If you want unlimited runtime, the corded Black & Decker HH2455 (*Est. $70) weighs about the same and also has a two-year warranty.
