“"Added the edger attachment later — the split shaft is a genuine feature, not a gimmick. Now I have two tools for one battery."”

Battery not included in tool-only listing — I ordered the base trimmer and didn't realize until it arrived. Make sure you're ordering the kit version if you need the battery.

Seven pounds gets heavy after extended trimming sessions. My half-acre property perimeter takes 40 minutes and my arm is tired by the end.

Line feed jammed the first three times I loaded it. Once I figured out the correct winding direction it's been flawless, but the manual doesn't explain it well.

More expensive than Ryobi or Greenworks alternatives but the 56V power and EGO battery ecosystem justify it if you're already in the EGO family.

Owners report enjoying it alongside the matching EGO mower, and are generally happy with performance. The one real limitation mentioned is with thick, woody stalks late in the season — one owner says they've resorted to hand-cutting tougher ornamental grasses rather than fighting the trimmer through them. Battery/charger sizing between the trimmer and mower also takes some getting used to, though it's framed as a minor tradeoff for lighter weight. Good pick for typical yard maintenance and mixed EGO ecosystem owners; if you regularly cut thick, woody growth, expect to supplement with hand tools late in the season.
