Query: Poor design

In theory, this is a good machine. In practice, it is not.The thermo-carafe sounds like a good way to avoid over-heated coffee that can become bitter. However, what happens when you put hot fresh-brewed coffee in a cold carafe? Its not hot anymore. Unless you pre-heat the carafe, only your first cup of coffee will be hot. After that, it cools rapidly.The AromaControl feature (steeping ground coffee for nearly 2 minutes to begin the brewing process) is achieved through a siphon action in the lid of the carafe. About half a cup of coffee collects before it is dumped into the carafe. I don't know if it really effects the flavor of not, but no provision was provided to clean the inside of the lid. You can pry it open with a butter knife, but its obviously not meant to be cleaned. Not good. The best coffee is always brewed from a clean coffeemaker.It sounds like Krups needs to hire a real engineer.
