2. Up Close: Real-World Reviews
EGO Power+ ST1521S
Why It Shines: I pressed the Rapid Load™ button and voilà—the line snapped into place in seconds. No more fiddling! The 15″ dual-action blade chewed through dense privet as if it were butter. By the time the battery hit 10%, I was already swapping in a fresh pack for round two.
Pro Tip: Keep a spare battery handy. A quick 30-second swap gets you back in action faster than refueling a gas engine.
Who It’s For: Anyone with a half-acre plot who wants gas-level power—minus the fumes and pull cords.
Makita XRU23Z
Why It Shines: Two 18V batteries give you a full hour of heavy-duty trimming, and the brushless motor hums so quietly that I could trim before dawn without waking the neighborhood. The automatic feed head means no “bump, bump” interruptions—you just focus on the cut line.
Pro Tip: Balance the batteries front and back—you’ll feel the difference in your arms after 30 minutes.

Greenworks 21212

Who It’s For: Beginners, seniors, and anyone with small to medium yards craving ultra-light equipment.
Black+Decker LST300
