It works but... - Hoppe's 9 Tornado Brush

It worked pretty well to brush off debris from my 12G beretta shotgun but brush part came off from the attachment base when I used it for the 2nd time. Maybe I had bad luck or pushed through the barrel too hard but I wasn't expecting this to happen in such a short period of time. I guess I can fix it by filling epoxy adhesive anyways so I still recommend this to other people because it works much better than regular bristle brush.
