Marvelous for brewing a full pot of tea and drinking it over 4 to 6 hours.
This is a fantastic item--exactly what I wanted in a teapot. It has thermos-like qualities that keep the tea warm for hours, though like any themos as you drink each cup some of the heat will be lost into the airspace replacing the hot liquid. I still use my Flying Tea Gourd as a thermos when not at my desk, but this has largely replaced it most days at work.The double strainer basket design is awesome. I brew my tea in the larger basket and remove it after 3-4 min of steeping to reduce bitterness. The plastic does not get hot to the touch and it is an easy to pull out. I tend to place it into a cup in case I want another, weaker pot of tea on a second steeping later.One can also leave the leaves in the basket and the upper stainless steel basket will make sure they do not get into each cup you pour. I do have one Irish friend I drink tea with who likes to leave the leaves in the pot forever and temper the bitterness with milk. That way, you don't even need to remove the inner basket.The design of this is amazing. The container pours well, seals well--I add honey to the pot and shake it upside down instead of stirring--and looks attractive.Probably the only thing that took me a minute to figure out was the button on top that controls whether the tea pours or not. The first time I used I thought I had to turn it to open it for a pour. Apparently I forgot to RTFM.Last, I am not a coffee person and such will never touch my own teapot, but I suspect that this design would probably work wonderfully for cold brewing coffee as well...
