This is the best teapot ever. It doesn't drip, the tea stays hot, and it cleans up nicely.
We found this teapot about 12 years ago. My FIL was a big tea drinker, he had a pot at breakfast, lunch, and dinner. He was forever frustrated by teapots that dripped so Hubby and I went on a mission to find him a better teapot. Store after kitchen store led us to an out of the way tea shop. Back when there really were no out of the way tea shops.
After he tried it I became convinced. I had a pot for home and one for the office. My MIL still has and uses the original pot we bought. When I would go on mat leave at the office it was a bit of a contest to see who would get my teapot while I was away.
The Henley teapot comes in multiple sizes and even different enamel colours. I like mine big and stainless. Many online tea stores have them now. Even the big A does too. Prices vary, so double check the size you are buying and shop around.
To be totally honest, it isn't perfect. If you don't keep it clean by rinsing or washing after each pot of tea the seal for the spout starts leaking. And it gets very hot on the outside with the tea on the inside. (When making loose tea I have to leave the lid off while brewing or it becomes impossibly hot on that little ball.) I can forgive it these faults completely because I don't have tea drips everywhere. And I can put it on the table without a hot mat below it. Plus, it looks pretty snazzy.
