Query: It's hot all right.

This gets my tea water hot quickly, which is what I was after, but it does so and then remains on all the time. It does not turn off automatically when water is hot, it doesn't even turn down when the water reaches the boiling point. It just stays on. I'm conserned that it will run dry sometime when I'm busy (I got this for work) and not paying close attention. I should have check out this product more carefully, I would not have purchaed this had I known it did not have an auto-off feature.
