It is a nice tool but not so great for trimming grass if that is what you meant. String line trimmer much better. Not sure what you mean by edging. Sidewalks? Beds? It works ok for either but then again there are other tools that work much better.
I ended up using it mainly on my own property maintaining bed and sidewalk edges. It would cut sod well. Cutting back flowers works well. Overall it comes in handy but not a daily use tool at least for me. At what they get for them it may be hard to justify cost IMHO. There should be someone who sells them online.
