Prior to ordering this item and putting it to use, I was struggling with a weed-eater to do my edging. Unfortunately, I was never able to get the hang of re-threading the spool with new line, and would have to stop and re-thread multiple times during each use. Also, I never liked the jagged edge the weed-eater would leave along the edges of sidewalks and the driveway. So I ordered this item in the hopes of solving both problems, and solve both problems it did. My lawn edges are crisp and clean, and I never, ever have to stop to reload that damn line, which means I get the job done faster and with less frustration and sweat.
