I like the idea, I live in the woods and burn a lot of pine and aspen. The only issue I see with the design is that the release button on the rods should have a dimple in it for the release tool to seat in. I used this for a woodstove pipe. I had to stand on a stepstool and feed the rods up the flue. To attach another rod the tool kept slipping off the release button. A dimple in that button would keep the tool from slipping off. Also, this is a 2 person job. We used a shop vac to catch the soot. I also took a 1 gallon ice cream bucket, and cut a hole in the bottom of it to feed the rods through, and then jammed the bucket - bottom first, into the open end of the flue, forming a seal to contain the soot. This worked well. Good product, I would recommend.Used on my wood stove stainless steel pipe. Normally I would go up on the roof take off my chimney topper and run fiberglass rods down it with a nylon brush. Very time consuming and dangerous it’s about 35 ft to the top. This tool made it so easy and took me no time to finish. I would highly recommendI have a large Lopi wood stove insert vented via a metal pipe that goes up about 22 feet through a stone chimney. I have been having the pipe professionally cleaned at the end of the winter season each year, and the draft is terrific for quite a while. But this year, I had a ton of great firewood, and burned a lot more wood than usual. With still about a month to go before the winter ended, smoke started coming into the room every time I opened the door to add wood. Rather than stop using the fireplace or possibly having to have the pipe cleaned twice, I decided to give this chimney sweep kit a try. And it worked great! The kit is easy to use, but it could make a terrific mess if you don’t have a good plastic barrier over the opening. Take a look at the accompanying pictures for how much creosote came down the pie, and how none of it came into the room. Here is what worked for me: 1) I put a layer of plastic inside of the door opening, and another one outside, and taped the top and side edges with duct-tape, and left the bottom edge untaped at this point. 2) Then I put a few strips of duct-tape in the middle of the opening about a third of the way from the bottom, made a vertical cut through the tape and both layers of plastic, and put about a 6 inch long piece of black plastic 1 inch pipe through that opening at an angle so that the rod would go up into the flue as I fed more rods into the pipe, and taped the black plastic pipe in place. 3) I then put the head assembly onto the first rod, ran the head and rod under the plastic with the head going into the flue, and the rod coming back out through the plastic pipe, and then sealed the bottom edge of the plastic with duct tape. 4) I used a good electric drill and made sure to keep pushing the head up and down as I ran the drill (as others suggested) adding more rods until I could feel that I had reached the top, then did the same on the way down as I removed the rods. The rods slid easily in and out of the black plastic pipe, and none of the massive amount of creosote came through the plastic barrier or the pipe. The whole job took about an hour. Detaching the rods on the way down was sometimes difficult but the pointed end of the tool that is provided worked (with some effort) to press the buttons down far enough to release the rod. When cleaning the rods, I suggest spraying each button with WD40 to make it easier next time. That may even make it worth doing before first use to make sure all of the buttons are good to go. All in all, a great tool and well worth the price!This is a great product I was able to clean my 8” round chimney with a offset no problem. This kit is perfect for a chimney that isn’t perfectly straightI had never heard of cleaning a chimney from the bottom but it works great!The kit is super easy to assemble and use. I couldn't see paying someone $200 for less than an hours work to clean my chimney. I'm amazed at how clean the brush got my flue using just my battery powered drill and there was no damage as they are nylon bristles in the brush. This product paid for itself the first time I used it and allows me to clean the chimney without having to wait on someone else to do it. I can see many years of using this kit in the future.The rods came apart a couple times but can’t say it wasn’t user error. I’d recommend this chimney sweep. Sorry I’m not much of a writer nor do I do reviews very often but I thought this one was deserving.I live in a remote area and finding a company to come sweep my wood burning stove was not happening. I bought this and was surprised at the ease of set-up, use, and overall functionality. It was easy to not make a big mess and I was shocked at the amount of creosote I had built up prior to use. My 18v Drill handled it with no issue.with only four inches of clearance from the ground,i easily cleaned my mother's chimney....beats going up on the roof anyday
