Great tool, but can be dangerous.
It did what it was designed for. However can be a bit dangerous if used in tight situations. Just like a skill saw. it can catch on something and pull the trimmer head away/run out on you.
In my experience while trying to eliminate the stumps of some 1"-2" diameter trees that had grown up near a chain link fence I bumped it against the tree on the wrong approach while spinning and it "took off" & tore a couple of very clean slashes in a chain link fence post. Upon inspection, the cut heads were all in tact an solid and still kept cutting afterward. But the saw did need sharpening as it was not as efficient after the fence pole contact, yet still finished the task and a few dozen more cuts I had started.
Be sure to wear safety gear including safety glasses, heavy pants/jean, and steel toe shoes.
