Excellent whistle and boils at half the heat. Top is removed for filling and pouring. Exactly what I wanted in a whistling tea kettle. A very hard to find item. I could not find one anywhere but on Overstock.com.

The black lid/plug has a little lift type handle. It's small and you must lift from the back or the steam will burn your fingers. The glass seems a little thin/fragile. But so far it boils, whistles and pours just fine.

I've always liked the look of Glass on my stove It's light weight easy to clean and looks great! And at a great price easy to use.
