It works so much better than the cheaper light weight one that I had been using. It scrubs the chimney liner clean in just a couple of passes. It is almost fun to brush out the chimney now. I'd recommend using the heavier 3/8 rods if you need more than two rods to reach the bottom of your chimney. Seems like a lot of money for what it is but it really works good, and the cost will be made up by cleaning your chimney yourself.
