Input:
This was supposed to be a high end tea kettle, but when I tried to use it I found two major problems: 1) The "whistle" feature only works about 50 percent of the time. Several times I found the kettle boiling away (with the whistle nozzle firmly in place!) and not making a sound. 2) The handle gets very hot when you heat water - easily hot enough to cause severe burns. Yes, the kettle comes with a quilted, slip on hot pad for the handle - but if that gets lost, or (eventually) wears out - I don't want to have to worry about friends and guests not knowing you have to use a hot pad to take the tea kettle off the stove.
If I'd paid $12.99 for this tea kettle, I wouldn't have minded these problems. For $100??? I expect a tea kettle that works much better than this. I've returned it for a refund.
