Value for Money
From my perspective, this line is a good investment if you do regular yard maintenance. It may cost a bit more than basic trimmer line, but I found that the longer life and stronger performance helped make up for it. I would rather spend a little more on a line that lasts longer than replace cheaper line repeatedly.
