Query: Boils well

This teakettle is essentially the same as the one I used for a dozen years and decided to replace for aesthetic reasons. The copper bottom makes all the difference--stainless steel bottms are unacceptably noisy as they heat up. However, the new kettle is inferior in one way to my old one. Apparently the copper bottom is not the same guage metal as my old one. This one taks longer to bring to a boil. One advantage though is tht the whistle is louder on the new one--you can hear it in another room. The trigger-like mechanism for opening the kettle top on the new one rattles in a way the old one didn't. On balance, the Revere is the best teakettle available because of its copper bottom. I know because I've tried a number of others.
