I have it and it works pretty well. Doesn't do a good job in wet soil, a bigger machine is much better in these conditions. I always hit the edges twice. It will cut new edges in, go slow for the first cut, then clean it up with a second go. The second go around makes a big difference and doesn't add much time. Its great for tight tree rings. I like it. Obviously not as powerful as a pull behind unit, but its light weight and maneuverability makes up for it. Most mulch jobs I just include this service in the price at no additional cost. its quick and looks good. We also swap out the bit for a regular edging blade and use it for sidewalks as well to get even more use out of it. I wish it had a larger engine. The aluminum guard has also needed replacing twice as it cracked in the same place both times.
