At first I was very disappointed because the machine had a few -a-day period, taste the coffee machine and to Rubber! Did the device already send back. Then this has aufgehört- "bitter aftertaste", though it now also tasted the coffee as it should! 1 star deduction: I can until now, the use of non-coffee-onset without seeing there! And what I would like to mention: I like to drink a little bigger cup of coffee, - and the filter insert for 1 person- extends best case for an espresso! The larger the filter insert is completely ok! You have to know it stop! Easy to put But- this Betrag- a good coffee and by the square shape too!
