The Owner-Style Take
Opinion
My read: Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210) is not a universal recommendation. It earns its place when the use case is narrow and real: Buyers who want premium battery-trimmer performance at a value-tier price and don't need the larger EGO ecosystem.
The reason to keep it on the shortlist is Strong 80V torque at a sub-EGO price point. The reason to slow down before buying is 80v pro ecosystem is smaller than ego 56v. I would not treat the star rating as the decision; I would treat the yard, storage, maintenance tolerance, and five-year cost as the decision.
If you are deciding between this and EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S), start with the failure mode you are trying to avoid. Pick Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210) when the notes below describe your lawn more closely; pick EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S) when its compromises sound easier to live with.
Pick It Over
- Pick Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210) over EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S) when you already own Greenworks 80V batteries or want lower upfront pricing in a premium-voltage kit.
- Pick Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210) over DeWalt 60V FlexVolt 17" Brushless Cordless String Trimmer (DCST972) when its fit matches your yard better than the higher-rated alternative.
- Pick Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210) over Milwaukee M18 FUEL Quik-Lok String Trimmer (2825-21ST) when its fit matches your yard better than the higher-rated alternative.
Skip If
- - You are already locked into a different battery platform and do not want another charger and pack family.
- - 80V Pro ecosystem is smaller than EGO 56V
- - Service network lags Toro, Honda, and DeWalt
Five-Year Cost
Estimated five-year cash outlay: $290-$530. That includes the current street-price range plus string, blades or heads, and a possible battery refresh if this becomes your main yard tool; it does not assume a paid repair shop unless the category commonly forces one.
Greenworks Pro 80V 16" Brushless String Trimmer (ST80L210): Editorial Assessment
Greenworks 80V is the value play in the premium-battery trimmer set. It has the voltage headline, a 16-inch cut, brushless motor, and kit pricing that often lands below EGO, DeWalt, and Milwaukee. That makes it easy to recommend to the buyer who already owns a Greenworks 80V mower or blower. It is harder to recommend as the best fresh-start ecosystem.
Pick it over EGO when you already have 80V packs or the lower kit price matters more than POWERLOAD and EGO's broader outdoor lineup. Pick it over Black+Decker when you need actual torque and a wider swath. Pick it over Ryobi only if you are already in Greenworks or want the 80V platform specifically; otherwise Ryobi's Home Depot support is simpler.
The owner complaints to take seriously are line-feed and detail-edging frustration. This is a strong residential trimmer, but it is not as polished as the best EGO setup or as contractor-coded as DeWalt/Milwaukee. The 2Ah kit is enough for normal weekly trimming, not a guarantee for brushy cleanup or fence-line neglect. Five-year cost is best when the battery does double duty across mower, blower, and trimmer. If this would be your only Greenworks tool, compare the whole platform before buying the kit.
