This is a great tool. Compared to my old gas powered line trimmer, this was a pleasure to use. It is light-weight and well balanced and cuts just as good as a gas trimmer. The best thing is that it is so quiet. All you hear is the whirring of the line. There is no motor noise. A fully charged battery runs over an hour, (about as long as a tank of gas) and only costs pennies to recharge. I like not having to deal with mixing oil and gas (let alone paying $3-4 per gallon), pulling a bunch of times to get it to start and having to adjust the carburetor.
