Got this edger about a month ago. I've only used it a few times and works great! Takes some getting used to find where your edge needs to be. Plenty of power to edge sidewalks, driveways, etc,
This is a quality tool. It’s powerful and the battery has a lot of juice. I have St. Augustine grass, and the long-neglected runners can be hard to cut, so a sharper edge would be helpful. Once I get my lawns into better shape, this will suit my needs very well.
This edger is a beast, it has plenty of power. However, it's heavy, especially with the battery inserted and somewhat awkward to maneuver on its one wheel and skid plate. It works fine along the straight edge of the driveway, but difficult to use along the curved curbing surrounding my landscaping. The blade will spark against concrete and looks like it will probably wear out pretty fast. Have used it 4 times. While it cuts a nice deep edge, my string edger was much easier to use.
In the past month I have purchased the 80 volt lawn mower and edger. Note: its only been a month. Both tools work perfectly and are much easier to use than a traditional gas powered tool. Push button start is a great feature and the power seems to be equal to a gas powered tool, no mixing of gas and oil or the smell. Much quieter as well. I suggest the 80 volt because of the power. I do have a small yard, so on one charge I get three cuts and edgings. I plan on purchasing the blower next. If the snow throwers had larger wheels and power assist I would think about that as well.
