Have the Grillbürste now already used about 10 times and can recommend it with a clear conscience. It is of robust construction, the bristles are made Edestahl and have to stick to exactly the right distance for a good cleaning performance without Grill by residues. The bristles are made of copper is not claimed as from time to time - but I do not exclude that there is a second version of the brush. I would recommend the course only brush with a decent (stainless steel) Grill (rust). Colleagues with chrome versions are very quickly getting the chrome grilled :)
