I didn't even think I needed to do this, I just used a CSL log a couple weeks ago, but the future wife was scared so I shopped around for a chimney sweeping service, $200 to $350 quotes... I didn't want to pay that much, I thought there must be a way to do it myself, then I found this tool, this particular one seemed like the best deal on Amazon (there are dozens to choose from).... Do I got it and I did it myself pretty quickly and you can see the results, I don't really need to say anything here, I should just let the pictures do the talking.... This kit comes with plenty of 3 foot extensions and two brush heads, it works easily, and it seems very durable. Keep the box, it's a pretty nice cardboard box to store everything in....
