Soon after purchasing the American Gardener YS24 I quickly learned why it is necessary to buy name brand quality products. The first season I used this product the plastic head of the YS24 spool needed to be replaced. Soon after the spool cover broke. Both parts are made with thin soft plastic that wears out quickly. Now I have a trimmer that is not useable because I can't find replacement spool cover parts anywhere! The YS24 didn't last one season. Please reply to my review if you know where to get the replacement spool COVER if you know where to get one?
