Who should buy it?
A good fit if you…
- The Greenworks 40V 12-inch is right if: you have a small to medium yard, want a genuinely complete kit at a budget price, and value warranty length over premium
- Consider alternatives if: your yard is larger or has regular thick growth, in which case the EGO ST1521S or Husqvarna 128LD are better suited, or if you want a

What You Are Buying
The Greenworks 40V 12-Inch Cordless String Trimmer is a budget-tier cordless trimmer built around Greenworks' 40V battery platform.
The head uses a dual-line auto-feed system and the trigger is variable speed, letting you dial back power on lighter tasks to conserve battery.
Performance
Everyday lawn trimming: handles typical grass and light growth comfortably.
The 12-inch swath means slightly more passes than a 15-inch trimmer on a larger lawn, but it's proportionate to a small to medium lot.
Edging: the head pivots for basic edging use, though the mechanism feels less solid than the EGO's or Worx's pivot design.
Battery runtime: the 2.0Ah battery is the smallest capacity covered in this category's lineup, adequate for a typical small-yard session but the first to run low on a larger property or in dense growth.
What It Does Well
Including the battery and charger at this price is the trimmer's biggest advantage.
The 3-year warranty is genuinely longer than most of the category, a meaningful hedge for a budget-tier motor and battery that are more likely to show wear over time than premium components.
What Falls Short
The 12-inch swath and 2.0Ah battery are the clearest limitations.
On anything beyond a small to medium yard, or with any regular encounter with thick weeds, this trimmer runs out of both cutting width and battery capacity faster than the pricier options in this category.
Build materials are noticeably more basic than the EGO or even the Worx, though this is expected at the price and doesn't affect day-to-day function for light use.
Who Should Buy It
The Greenworks 40V 12-inch is right if: you have a small to medium yard, want a genuinely complete kit at a budget price, and value warranty length over premium materials.
Consider alternatives if: your yard is larger or has regular thick growth, in which case the EGO ST1521S or Husqvarna 128LD are better suited, or if you want a lighter trimmer with two batteries, where the Worx WG183 is the stronger pick.

Frequently asked questions
Is the Greenworks 40V trimmer good enough for regular use, or just occasional trimming?
It's suited to regular use on a small to medium yard. The motor and 2.0Ah battery handle routine lawn trimming and edging comfortably. Where it shows limits is sustained heavy growth or larger properties, where the narrower 12-inch swath and smaller battery mean more time and more charging cycles.
What's included in the box?
This is a meaningful value point since some competitors at a similar price sell the bare tool only.
How does the 3-year warranty compare to competitors?
Most cordless string trimmers, including the EGO ST1521S and Worx WG183, carry a 2-year warranty. Greenworks' 3-year coverage on this model is longer than typical, a genuine advantage for buyers concerned about longevity at this price point.
Can the battery be used with other Greenworks tools?
Greenworks' 40V battery platform is shared across its mower, blower, hedge trimmer, and other yard tool lines, so the battery and charger from this trimmer work with other 40V Greenworks tools if the collection grows.
