As far as a replacement spose go they're not really bad for the price works is slow on shipping them so make sure you order well ahead of time and the thing I don't like about him as they seem to be one so tight that when you stop trimming a lot of times the string will get tangled around the shaft
I purchased my Worx trimmer because I was tired of dragging a cord around the yard. My Worx trimmer does a very fine job cutting even thick, tall grass. My only complaint is how fast it uses up the string when edging the driveway and the sidewalk.
