I bought one of these as part of a greenworks package including a mower and a drill. It is a piece of junk. The filament breaks off every time I use it, and it is impossible to re-thread the spool. Plus, it is impossible to register their products online for warranty coverage unless you have a picture of the receipt, which Amazon does not issue. Finally, their customer service phone line NEVER, EVER answers…there is no email option. Avoid this company and its products…unless you need more useless plastic junk cluttering up your garage. Cheers!
thank you
Gracias!
