Query: Fun in the Beginning; Quickly Loses Charm

Bought two in the past year-- won't buy another. This coffee maker was great fun to watch at first-- volcanic action right on your countertop. Coffee was also good at first-hot and strong with the taste of the "oils" from the coffee beans. But clean up is messy, and the carafe is virtually impossible to clean without getting the electric base wet-- which is what ended up failing on both our machines. Also, the filter has to be changed frequently or the coffee will taste muddy. Too much money for what initially was a fun "conversation piece".
