This tool was great I am very happy with the performance so far. I have used it twice but I appreciate the fact that I can expect it to start every time. The question is how long will it last we'll see.
The weight of this is perfect! The batteries last a good 35-40 minutes on a full charge and recharge quickly, so if they do run down, you're up and running again after a rest break. I'm taller, so I had to move the handle lower for better balance and to use on my hills, but that's a personal preference.
I love my weed trimmer, its so easy to use and so much lighter than a gas powered trimmer. It does a fantastic job trimming. My only complaint is it takes a little work to refill the line. I would highly recommend this trimmer.
