Bests & Worsts Reviews from Amazon

This is a good trimmer. It cuts well and I really like the vertical, rotation feature to allow you to get a nice clean line at the edge of your lawn. However, one MAJOR complaint. It is designed to automatically release some of the plastic twine periodically. This is pitched as a nice feature since it is supposed to detect when the twine is short and lengthen it as needed, as it naturally gets cut due to hitting rocks, etc. However, it releases twine needlessly every few minutes, instead of as needed. The excess gets cropped off by the spinner when it is too long. At the end of the season I can find dozens of one inch lengths of twine all over my garden from this thing - all the same length. More importantly, this means you use up spools of their proprietary twine extremely quickly. Since I bought the trimmer 3 years ago, I've gone through an incredible 10 spools of twine! At this point I'm convinced that it is deliberately designed this way to sell spools of twine, like Gillette's razor / razor blade business model. I originally bought the product for $54, cheap, right? I've now spent $68.65 on spools of twine for this thing, and I'm still going strong! I see that the trimmer now sells for $41.65. All the more enticing to get customers on the Greenworks train and hooked forever! It's a dirty trick and extremely annoying.
