I bought this product after changing the head on my trimmer purely for testing purposes. Both the thickness and shape of the trimmer line make it quite durable, resulting in hours of cutting without much wear and the need for frequent replacement. It was used on a property to clear grass and weeds that had grown around the fence grids. I was very satisfied as it literally ate through the weeds while also not getting tangled in the grid, unlike other trimmer lines I have used in the past. One positive aspect is the low cost!

In the first test, it lifted even rocks without any damage, in combination with an aluminum craft head. Below is the review and test, I will come back if anything changes
