The noise level is 50% lower (7–8 dBA) compared to round lines of the same diameter. Reduced air resistance helps the engine reach optimal speed faster and increases efficiency.

The line is made from a unique material that does not fray at the ends. Thanks to its special surface, the risk of fusion (sticking) inside the trimmer head is minimal. It features high resistance to wear and a long service life. The line shape reduces the risk of breakage at the outlet hole.
