I've had my WORX trimmer for 2 years. Because of your simple to follow procedure to replace spools, I am always prepared to use my trimmer. It is easy to do this on line and orders are mailed promptly
This was my 5th season of using my Worx wead-eater/Trimmer and although the spools are small, they last quite a long time. One of the best issues with the Worx trimmer, is that my wife actually likes to use it, where she would not use the gas trimmer I had.
