Wife does the mowing and weedeating, granted we have a LOT to do, but I bought her a small gas one... Nope she came back saying it didnt' cut well and she could stop it by pushing hard into stuff.
She finally ended up with a big commercial quality Stihl one. I don't think battery would work for her and thousands of feet of fence she does. LOL.
The battery op chainsaws aint' bad for thumb size stuff, a buddy has one, trims ok around deer blinds for thin stuff, beyond that, the echo on a pole I have thats gas run... whoops the batt ones azz
