Customers are mixed about the quality of the string trimmer. Some mention it's a strong weed whacker that clears grass and weeds, the trimmer itself feels sturdy, and it is heavy duty. However, others say that the string system is not good, the swath is too small, and the line breaks far too easily. The advancement of the line is still an issue, and some customers report that the pre-loaded string holders jam almost immediately.

Greenworks 40V string trimmer
This is a powerful trimmer. I have not had double-sided line and there is a difference. Not sure about battery power. It is not lightweight but seems to be balanced. There is a bracket enclosed that you could rig a shoulder strap to. I plan on doing this next- taking the one off my old trimmer. Some people complain about the tough safety button you have to depress to be able to use the machine- this is valid! I set about trying to turn it off but came up with a better solution! Take all the screws out on the right side of the housing (some of the screws are very deep in) but once they are all loose you can pry it half open. The black cover keeps you from taking it all the way off- don't worry about that- look in to where the triggers are and you will see the spring you see in the enclosed picture- TAKE IT OUT. The safety button is now VERY much easier to press and will not fatigue your thumb. You're welcome!Update: This trimmer uses .065" line. You will need to buy replaceable "cartridges" or have that size line on a spool. There are YT videos to instruct winding the lines- it doesn't look totally easy but i am determined to use the line I have bought! The battery seems fine and definitely lasts for all of the trimming I have to do around my 2 acre property. My old B&D trimmer would take two batteries worth of power, a pain to change since you are always the furthest distance from your 2nd when it dies.. I rigged up a shoulder harness as well. Just took it off my B&D and put the bolt through the bracket that is on the Greenworks shaft above the black handle. Makes it much easier on the back when adjusted properly!
