Hello, am to be happy the only thing that bothered me at the beginning that one tank diagonally purely translated needs. The descaling is easier than ever before, it's all automatically You just have to change the water. The Machine turns off when the machine is descaled. And the machine displays from when it is calcified :-) The Britta cartridges I could not test as I have decalcified at the beginning and the cartridge was left in it: - / The tank is huge clearly recommended for a lot of coffee drinkers who drink only 2 cups per day ordered a smaller version. Another practical feature is that you can simply take out the lower part and a bowl etc can make less. The price I think high, with a 50 Senseo you get the same taste just stop without the extras at :-)
