Customer Reviews
Customer Review: “The Worx edger works well, did a nice trench for lawn edger strips, too. Happy with the way it works, pretty basic, I’d recommend you use this on a dry lawn, or you’ll be cleaning the blade frequently. Just be careful you don’t turn back across the cord’s path, or you’ll be doing some power cord repair.”
Customer Review: “Outstanding machine. It trimmed some of my sidewalks, that had not been trimmed in 5 years, like there was no overgrown grass.I bought this for my wife because of it’s features, mainly three wheels. That made it easy to use.While I was trimming the overgrown sidewalk it kicked up a lot of dust but that was to be expected, not the machine’s fault, mine for getting letting the sidewalk get in that poor of a shape.I most defiantly was worth the money.”
