Very good. I bought it for a Bosch machine, as others have mentioned, and it fits perfectly. It does the job at a reasonable cost. 40 meters should last for years logically. It is very easy to cut to the right size. If I need it again, I will buy it again

I put it on a Bosch AFS 23-37 Electric Brush Cutter Shoulder/Handheld 950W 5.3kg and it fit perfectly. It also lasts as long as the original.

Hard, strong trimmer line that doesn't cut with anything, even in direct contact with stones and thick branches. It literally mows down and wears out much later than other branded twisted ones I used. The 4.5mm one I use requires a powerful brush cutter.

The first time I bought it by chance at a local store to try it for professional use. This thing doesn't break, I clean until the edges melt and then I change it, even in bushes its durability is huge. Be careful to measure and cut it correctly after stretching it well when you put it on the head, so it’s not too long for the machine and doesn’t strain it.
Because I couldn't find the product again on the island where I am, I had to order it because it is incomparable.

Very durable, it only gets cut by grass with a solid woody stem and a diameter over 1.5 cm (e.g. wild walnut - "smelly walnut"). The only "problem" is that it twists. I will also try those with a thickness of 4.0 mm and 4.5 mm. Agroforce guarantee!!!

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.

Quite a powerful trimmer line. I trimmed the edges of our yard, totaling about 150 meters (front fence inside and outside and the entire rest from the inside on about one acre of yard), I didn't even need to put in another, it didn't break and I was hitting the concrete or the stones where it had them.

The next time I used it on thicker grass, it broke at some point. Overall, I am satisfied with this trimmer line compared to others I have tried.

I use it on this head:
