Black & Decker NHT518

Bottom line

For large yards where corded trimmers aren't practical, the battery-operated Black & Decker NHT518 is a reliable, lightweight choice. However, users recommend having an extra battery on hand to ensure the whole job can be completed in one go.

Performance

Cuts well and is ultra-portable. Reviewers praise the overall trimming ability of the Black & Decker NHT518. Some Amazon users even say the trimmer exceeds the manufacturer's claims regarding the diameter of twigs that can be cut. One such user says, "It states it can cut branches 3/4 inch, and it is true. With enough tenacity, you can cut up to 1 inch branches." However, not everyone is pleased with the battery. The most satisfied owners are those who use other 18-volt Black & Decker products as they find the interchanging batteries convenient and quick to change.

Ease of use

Great for short jobs. Most users say the Black & Decker NHT518 is easy to use. The unit's light weight makes it possible to trim the tops of hedges with only one hand, users say. However, having to charge the battery in the middle of a long job can interrupt workflow and prolong otherwise quick projects. A single charge will last longer for light work than for heavy trimming, but most reviewers say battery life lasts less than 30 minutes of standard use.

The locking power trigger adds an element of safety. When the button is employed, the machine cannot start, thus reducing the risk of unintentional cutting. The built-in hand guard is effective, as YouTube user "SunBaskingMan" demonstrates in his video review.

Noise

Electric quiet. Users find the battery-powered Black & Decker NHT518 much quieter than gas hedge trimmers. "It is silent and powerful," one Amazon shopper says. "You can get a lot of work done without worrying about disturbing your neighbors." Because it is battery powered, it vibrates less than gas trimmers, too. "I love the low vibration," one Amazon user says. Another quips, "After trimming with this cordless, even without earplugs, I could still hear." Although some reviewers state they feel comfortable using the hedge trimmer without covering their ears, manufacturers recommend always using eye and ear protection while using power tools of any sort.
