Greenworks PRO 16" 80V Cordless String Trimmer

As an owner of a Greenworks blower and edger, I'm happy with those tools and expected their weed whacker/trimmer would be great -- boy was I wrong! For a strange reason, the trimmer starts off very slowly taking seconds to get up to speed. Once at speed it's powerful and effective. My head does NOT auto-dispense new line out! So when you break off the length of the line doing weed whacking, you have to stop, push the button down on the grubby head, and manually pull out some line. Expect to get your hands dirty! Once you pull more line out, then you can weed whack until the line runs out again -- and repeat that cycle again and again! Replacing the line is insane. Checking on many reviews and YouTube videos, there appear to be many different types of string heads that go on the 80v trimmer. Obviously Greenworks' engineers were doing improvements and we consumers were their "guinea pigs" testing the products they sold -- that's my guess. Replacing the string shows you it only takes a small amount of string. It's supposed to auto-load but good luck with that! You'll spend hours trying to feed the string in to get it to work right. YouTube videos for instructions won't save you, the Greenworks instructions that came with the tool are laughable -- you're on your own! Do yourself a favor and buy another trimmer/weed whacker.
