TABLETOP POT BT-015 1.5L BK

It's convenient because you can use it for both hot and cold drinks. When it gets cold, I make a pot of warm tea in the morning and it lasts almost all day. In the reviews, there is a comment that it makes a “thump noise”, but that's just because you fill it right up to the top and it's completely full up to the spout. If you don't like the noise, just don't fill it right up to the top.
