I bought a 3m length and two 1m lengths as I wasn't sure how much would actually go in once the height of the pot was accounted for and whether it would go around the bends. In the event I secured all 5 metres, which fitted very neatly and overlapped. Looks to be good quality. It was tight, but it all pulled in. I definitely suggest that the leading end is very secure as a lot of force was required pulling it in.
Had to wait a bit for liner but was fine when it arrived Stove was delivered 10 days after we ordered it which was exactly what were told .Now stove is in we are very pleased with it. Thanks to Arran who sorted for us .
Good quality ,easy to install,very pleased.
