Well, been a while but because of the weather only really used this in earnest during the last week. I'm impressed, it's as good as I hoped for. Cuts through very rough grass and new brambles with ease, and no messing with anything, pick it up and go. It's quiet, no need for my ear defenders anymore. Battery doesn't last that long in those conditions, but to be honest I don't want to strim for more than 30 minutes at a time.
The line has broken off once so I was left with just one, but easy to take off the head, remove the line completely, and then the best part - you put the head back on, re-thread the line straight through the head so you've got an equal length either side, press a button and it winds it in for you! Definitely the best strimmer/brushcutter I've ever bought!
