(Almost) completely zurfrieden!

For frequent overflow problem: Since the passage valve of the filter insert is blocked by a brewing process with a pen (so nothing drips), you have to use necessarily before reuse coffee brewing pull out (once briefly rinse) and reinsert it. Thus, the pin retracts again, the valve is open again. In the manual with me an extra piece of paper was there, who pointed out. If you change only the paper filter, the valve remains closed, which then of course all comes down!

The price I find a little bit too high for a "simple" coffee. This is in itself is very neat and beautifully finished, but the pass valve device of the filter cartridge and the water tank could have / be thicker a little more stable.
