I must say that I am impressed with th quiet line. not only does it let me listen to my peltors better when string trimming, it seems to slice through the grass, instead of tearing it. I was a bit skeptical of how strong the line would be at first, but it has just as much durability as the echo crossfire line that I was using. the only thing that I didn't like, was that my trimmer blew out more smoke when I used the quiet line, but it could have been the tank of gas I was using. overall: great product!
