Pros: The temperature settings are great and it keeps the water at the selected temp for 30 minutes. Quiet beep lets you know when it's at temp. Cons: The START button is also the off button (don't know why the developers couldn't label it both). It is difficult to determine when to stop filling the kettle. Unable to see very well into the top opening when it's filled. It should never be filled entirely, otherwise it will boil over. The headroom is important. It's probably difficult to clean as well since there's little room to see past the lid. Presumably, it doesn't need to be cleaned often.
