Watched the same thing happen with my own feed and now I scroll right past anything with a wide open mouth and a red circle. The whole fake shock thing feels like a salesman yelling at me from a car lot, and it makes me trust the video LESS before I even click. Give me a plain thumbnail and a title that just says what the video is about any day.

The kinking is the real killer with those kits. The rods are thin walled junk that fold the second they hit any real resistance, and once a rod bends even a little the brush stops spinning true and just polishes the glaze instead of cutting it. What makes it worse is that glazed creosote is basically plastic, it does not crumble like the fluffy stage stuff, so spinning a brush on it just heats it up and smears it around. I have heard the rotary setups work fine on soft soot or a stainless liner where there is nothing to snag, but on a brick flue with shelves and offsets you need something that scrapes, not spins. Your flat wire brush on a rope biting into the corners makes way more sense for that kind of job, and 40 minutes for a whole flue is honestly a good day.
