Cleaning chimney flue is an important task that is best performed from below. This device makes this possible without compromising personal safety or effective sweeping of creosote from the flue. It is well made, easy to use, fast and should last for many future uses. The kit is especially useful for higher runs as it has rods for up to 8m. The (minor) quibbles are lack of supplied plastic sheet to reduce dust which is included in other (more expensive) kits and difficulty separating the rods. Latter solved with a smaller allen key than the one supplied. Also needed are tape to attach and seal the sheet and a dust mask. YouTube has many examples of how to this works. Afterwards, I checked the flue from above and it was cleaned beyond my expectation.
