I would recommend an unpainted pot

The insulation performance is good. Even after 10 hours is still too hot to drink directly to him the tea. After 24 only lukewarm and almost cold.

Whether the pot is 100% tight, I can not say 100%, however. A tip for those who believe that the pot is not tight: If one has taken something to drink and then the shutter is closed, you should turn the pot again, as always a few drops contained in the locking mechanism. This drop could lead to the assumption that some writing here that the cans are not very close.

What I do not like the pot: the outer coating. Looks good at first, but now comes from this. First, the bottom of the pot and the cup where they stand. Where the coating is already off, it bursts from kicking on. I would definitely advise to an uncoated version of this pot. In the long run makes the optically certainly more ago.
