Black & Decker NST2018 18V 12Inch Grass Hog String Trimmer Black & Decker NST2018 ,Ship Free!

I bought this for my father who is approaching 70 years old. It is very light and very easy to use. We have burmada on our lawn. The first time we used it, there was a lot of growth so it took three batteries to finish his lot. I do have to point out that he had very bad technique. After I showed him a better way to do it, it worked more efficiently and now if he or I use it once a week, I may be able to get by with one battery. Because it inverts, I can do 40 feet in about 30 seconds, if you edge frequently and don't have massive growth. Just don't push it too close to anything you are try to get rid of, it slows it down and it doesn't work properly and the line won't come out. It has a 12inch area so remember to utilize that. I've also have edge and trimmed the yard 9 times this summer already and I still haven't used the spool of line yet. With our gas one the work would take about 45 minutes and I would have sore back from the extra weight. Now I complete my work in less than 15 minutes. This has been a pleasure to use.
