It finishes very quickly and breaks into pieces even in use ONLY on grass!! Maybe I got a defective batch!

The best trimmer line I have used on my Bosch Art 24 trimmer. It is much better than the trimmer line that came with my trimmer and even better than another one I bought from a local store which was 3-4 times more expensive! It is quiet, cuts very easily and quickly, even through tough and woody weeds, without breaking! For the first time, I don't worry about hitting something harder and the trimmer line getting cut. I worked for hours without stopping at all to fix the trimmer line. Excellent! And especially at €0.90 for 15 meters, you can get it without hesitation.
