Chamber cleaning tools

Do any of you have any experience with these tools, and if so, do you recommend them?

I've always made my own, but this looks like a more professional way to do it, with a tool that has been bent to just the right length.

A year or so ago, I looked for something like this, didn't find anything I liked, so I improvised.

No and No

That was quick - maybe you saved me from wasting some $$.

What I use now is a slightly oversize bronze brush, which I screw into an old S&W holder that doesn't let the brush rotate freely.  I turn the holder as the brush is going in, then turn it some more, and then pull it out while turning the same way.  I used to use a piece of tape to limit how far into the bore I push it.

I found this earlier, and it seemed intriguing as you can't push the brush in "too far".  Thanks.

without an explaination why, it's no different than thousands of shooters using a bent .24 caliber bronze brush for a few bucks.
