The heavy-brush answer: 60V FlexVolt, a 15/17-inch adjustable swath — the widest in the homeowner tier — and a 9.0 Ah pack in the box.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It is the heaviest trimmer here. 13.5 lbs with the 9.0 Ah pack fitted — eight pounds more than the WORX, and an hour of edging is genuine work. It also runs 0.080"/0.095" line, not the 0.105" the Ryobi and the Husqvarna pro tool take.
Dealbreaker? Runner-up №1 takes 0.105" line at 13.3 lbs ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you need a commercial/professional-grade trimmer for daily crew use
- you prefer gas-powered trimmers
- you only need to trim a very small patio or balcony
- you want a hedge trimmer (different tool, vertical foliage)Cordless hedge trimmer verdict →
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the DeWalt DCST972X1 is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
Kit vs tool only
The same trimmer lists 40-50% apart depending on which SKU a retailer stocks. The Ryobi RY402110 at $223 is TOOL ONLY — no battery, no charger — against $249 bare / $329 kit at Pro Tool Reviews, and Amazon titles routinely omit the difference. Every other row in this comparison is a kit.
Runtime on paper
Quoted runtimes are manufacturer estimates under moderate load with one named battery. Heavy weeds on 0.095" or 0.105" line cut them by 30-50%, and a 2.5 Ah kit runs roughly half as long as its 5.0 Ah sibling.
Gas-equivalence theatre
26cc, 30cc, 31cc, 1.76 HP — every gas-equivalence figure in this category comes from the manufacturer's own marketing and was measured independently by nobody. Line diameter is the real spec: 0.065" binds in thick weeds, 0.105" clears brush.
