I love this thing!
I’ve owned this kettle for 4 months now (since Aug 2013) and use it every day throughout the day. When using a baking thermometer, the temperature comes is about +/- 1 or 2 degrees within the desired temperature which is pretty accurate to me. I couldn’t be happier.
If you held a gun to my head and asked me to tell you something negative about this kettle, the only thing I’d come up with is that the ink on the Green Tea button (175 deg) has worn off from constant use.
