product does the trick. Great for cleaning small diameter copper pipes & other small delicate mechanical parts. Wish it came with a screw driver type handle.

I cleaned my battery cables off with ease with this tool all those years of a wire brush are long gone now

The small one that I just used got badly woren after one use

Used them to clean brake caliper brackets, work great until they break.

These are alright. Once you use them a couple of times the bristles get matted down which makes them more difficult to use. I broke one as well. They bend easily as well so if you’re not trying to do any tough work these are fine. If you do something that requires some force these are not for you
