I bought this edger along with the trimmer several weeks ago.  See review on trimmer I posted if interested in seeing that review.  Anyway, I am very pleased with the overall tool.  The only part I find lacking is the edge guide.  The blade sticks out further then the guide is and the blade is always hitting the walk way or drive way.  Even when you adjust the setting to the least amount of cut.  I would imagine this will wear on the blade quite a bit over time and bothers me but that is the only complaint I have.  The power of the unit is good for an electric one in my opinion.  I would buy it again if and when this one wears out.
