However after waiting far longer than it should take and hearing no whistle, I went over and took off the lid to see the water boiling

Gets water boiling quickly, but the whistle isn’t very loud and sounds strange

When the water boils, the lid whistles, not the spout--a novel approach

It gets too hot to pick up without a glove by the time the water boils, and I've burnt my hand more than once.

The new teapot has lost its "whistle" and I didn't hear the water boiling again and now this pot has burned too

This was a replacement item, for a gas stove, I like the shape and that it whistles when water boils.

It overheated as it did not whistle!!!!
