This little pot is the perfect size for one person, and truly keeps my tea hot for literally hours! The best I've ever come across. Tip: before you fill up the pot with your boiling water to make the tea, pre-warm the pot with hot tap water. That seems to almost double the heat retention time.
The only reason I didn't give it 5 stars was that if you are not careful it will drip when pouring. Cure: do NOT tip the spout any farther downward than absolutely necessary. Pour it slowly, barely tipping over, and it won't drip.
Other than the drip issue, it's great!!
