I purchased this last fall to replace some of my lighter duty equipment for home use but this is way too much weed eater for my small lawn. I literally used it one time and decided it was too big for my lawn.
If you already have Greenworks tools and don't need the battery and charger I can work with you on just the bare tool.
I purchased the Greenworks EXO Flex shoulder strap for an additional cost of $40.
