Bought these to clean diesel fuel injectors, found they didn't have brass bristles. Luckily I tested them with a magnet before using them. Advertised as brass at the top of the page but the description (which I couldn't read beforehand) says it's brass plated stainless steel. Why not just be up there with him? Anyway, I think they're good for what they are, but the level of misleading advertising these days really hurts me, hence the two stars.
