I've had this edge hog edge trimmer 2 1/4 HP for about 6 or 7 years. We use electric yard tools when we can because the cost is  usually less, little noise, don't have to keep gas and oil around,no gas smell, and simple to use, just plug it in and go. We have a hundred feet of outdoor electrical cord. Never came close to running over the cord, just have to keep flipping it from one side or the other,depending on the direction your going in. Lots of power for edging and deeper edging if you like and the lowest level has been great for taking up sod for planting gardens and  use it to keep our property sharp looking. Oh, this Black and Decker still works great. The first time you use it make sure your actually going next to the sidewalk, I've cut into our yard because I wasn't paying attention.
