Very good fishing line, does not cut easily and lasts a long time especially on rocky terrains is what you need. The black one lasts much longer

Very good, it lasts a lot (the black one lasts even more), quiet.
If you use it double, the machine should be 3+hp, otherwise in thick grass it will not reach full speed. The black one and some good Chinese ones cut marginally better.

Simply perfect, it withstands more than you can imagine, on a 6-acre plot I only changed it 4 times.

It withstands green grass, which makes it very cheap. However, if you have a powerful machine and go for rough terrain or even touch stones, it disintegrates in less than a minute!

Within 10 minutes, it got stuck twice, in cotton and small grass.. The black one is better and even double-layered, you can't understand anything. Stay away from this.

Update: I am changing my rating from 1 to 4 stars, because I put a double-layered one and it holds up well

The best product, everything else is just cough drops...
Although noticeably more expensive, it's worth every euro...
With the guarantee of vortex/nylonfaden and of course made in USA

Very good, it cuts everything even better without the guard. Hello, I have been using it for 3 years and I am satisfied
