I found it easy enough to use and bought another kit the same on account of I broke a section but it was my fault in the learning curve and now I have extra pieces, just in case. Sweep wanted $450 to come out here and clean one chimney and leave his paw prints all over the wall and soot on the carpet. This was my favorite purchase from 2022. Perfect for anyone inclined to DIY. Others have said the connectors are hard to manage. I didn't find that to be true but my hands are smaller so maybe it's easier for me to push them in.
