I upgraded from the 20v string trimmer. This has good power, works well, and is fairly ergonomic. I'm reading some bad reviews to do with the universal tool attachment - I didn't find the tools hard to change out (I also bought the brush head). I thought it worked as it should, had good battery life for how powerful it was, and wasn't too loud. Getting the handles balanced is an art, I think I'm still working on exactly where I want it. I think it would be cool to mount the battery on the handle center bracket, that way the balance of the tool wouldn't change if you used a different battery size (6ah vs 9ah for example). This tool is a bit much for my 5'2" wife - she doesn't care for it. Also, removed a star because it doesn't come with a shoulder strap. Weirdly, the brush head came with a strap - I found the brush cutter was a little lighter.

Batteries work fine spring and fall but do not stand up to southern summer heat...might not be a problem for it urban/suburban users but for continuous use out here on the farm the batteries warm to fast and take a long time to cool enough to reuse or recharge. Other than that, works well.

Good string trimmer little heavy but overall good trimmer. Power was good could be better

Great weight distribution and not super loud. Could easily use for any size lawn
