It's a nice looking rough teapot, very unusual. The only thing is it seems bit different than the pictures. Mine is not red tinged, it's very brown, the neck is shorter and the holding hand bit is very small, especially the round top bit looks smaller. I have tiny hands, so I'm OK but still not great to hold, but I can imagine it might be bit of an issue with people who don't have hands of a 10 year old, like me 😂
Only tried it with youngish sheng so far and it's nice, but haven't used it enough to say anything more about flavour changes.
