The price is good but the durability of the trimmer line is mediocre. What I mean is: if you use it for cutting grass that is not very tough, it does the job. But if you want to cut TOUGH grass, well... it struggles. I compare it to a Vortex VS170 that I had bought earlier, which, however, has twice the price of this one: I put two pieces of trimmer line on the head of the trimmer. To clean the same area that I cleaned with two pieces from the Vortex VS170 before they wore out, I had to put three times two pieces of the Agroforce, a total of six equivalent pieces. Another characteristic of the Agroforce trimmer line that personally annoyed me is that the pieces you put on the trimmer head don't stay taut but "curl up". I have never seen such a feature in any other trimmer line.
