I had one with programmable temps, I got it specifically for green tea. I then won a glass kettle, and when the other died I found it was just as good for watching temps by the size of the bubbles.I can't believe I didn't have one before now. I, too, am using it several times a day. I really love it!
I am getting to like the taste of green tea more, but can only drink it with certain foods. So far I've been doing ok having it with oatmeal and fruit
