The noise level is 50% lower (7–8 dBA) compared to round lines of the same diameter. Reduced air resistance allows the engine to reach optimal speed quickly and increases efficiency. Its unique material does not fray at the ends, and thanks to the special surface, the risk of the line fusing inside the trimmer head is minimal. It is characterized by long service life and good resistance to wear. The line shape helps prevent breakage at the outlet hole.
