This thing gets the edging job done. It takes a bit of practice to keep the line up against the concrete edge, and it won't turn gradual corners very well, but it seems to have plenty of power. I have a corner lot with quite a bit of bermuda, and that stuff will take over the sidewalk in a month or two. Personally, I wouldn't care, but my wife thinks we need to keep it edged, and so we do. Not sorry I bought it, and don't wish I had something better. It gets the job done, and I can get replacement blades at the big box hardware store, so no worries there.
