(checked 2026-10-10)Small sample (856 ratings). This is the tool-only ST1510T listing; the ST1511T kit adds a battery and charger.
Wirecutter's top pick: it cut through 1-inch knotweed, ran far longer than rivals, and loads new line at the push of a button. It weighs a little over 10 lb. Amazon owners report mixed durability, and some say the line won't feed out.
In the box: Yes in the ST1511T kit: a 56V battery and charger (Wirecutter says the charger fills the battery in about 40 minutes). The ST1510T on Amazon is tool only.
Top complaints
- Mixed durability
Durability gets mixed feedback in Amazon's review summary, and some owners say it broke during use. Wirecutter's test unit tore its foam front-handle padding after two years.
- Line sometimes won't come out
Amazon's summary flags 'cord removal' as a problem: some owners can't get the string to come out of the head.
- On the heavy side
A little over 10 lb, not the lightest Wirecutter tested. Weight is mixed on Amazon: some call it light, others heavy.
What owners love
- Top cutting power
Wirecutter says no other trimmer it tested topped its cutting strength; it cut 1-inch Japanese knotweed stalks like grass. Amazon owners say it powers through thick grass.
- Long runtime
An earlier version cleared about 3,400 sq ft of dense growth on one charge in Wirecutter's test, against about 2,100 sq ft for the next-best trimmer. Amazon owners rate battery life highly.
- Push-button line loading
Wirecutter calls POWERLOAD the easiest line-load system it has used: new line winds in within seconds. It uses a bump feed and the spool holds about 16 feet. Amazon owners praise the self-loading.
- You want a very light trimmer
- You have only a tiny yard
- You don't want to buy into EGO's 56V batteries
- Medium to large yards and overgrown areas
- Hating to rewind trimmer line
- Users of different heights (telescoping shaft)

What experts say
- Wirecutter (NYT): Top pick: unmatched mix of power, runtime, ergonomics and easy line loading, and one of the quietest it tested. The foam handle padding can tear.
