It came with a defect in the assembly that was beyond my ability to fix; fortunately my neighbor could because I didn't want to deal with returning it to Amazon.Pros: It mows the grass without problem, it is quiet and light. It doesn't use gas. The extension cord goes right into the mower so if you run over it you just need to replace the cord. Great priceCons: Dragging a cord around while mowing is a bit of a pain
