" ... As far as the trimmer goes, i love it. ... I was concerned something was missing or damaged but the trimmer works fine and everything was there. ... "
" ... So far the battery has proven long lasting and overall the trimmer is powerful enough for my needs, but I will be looking for blades that might fit the trimmer head so I don't have to stop occasionally and use the hand chopper since that is a bit of a pain. ... Overall the trimmer happily lives up to expectations, and I'm glad to not have another small engine tool that causes fussiness every time I need to start it, especially if its has been a while (like when I use my chainsaw only occasionally). ... "

Using the lower speed wasn't enough to get through the thick stands of grass and weed growth, but at high speed it did the trick, but I did follow the the suggestion to cut them down from the top in about 12" swaths, which made taking them down take longer, but it proved effective for almost anything I was trimming down except the little hardwoods. ...
