The pot is actually evaluate the design and the material quality with 5 stars. Unfortunately, it is not even worth a star on the capabilities. The inner part of the pot is processed inaccurately and thus runs the coffee after repeated use, due to a leak into the space between the inner and outer part. The coffee is poured out slowly and dropwise over the bottom on the table. Even in the 2nd pot that I got to share sent that was the case. Thus comes to mind that this functional failure is not an isolated case. Settlement of exchange and eventually refund through Amazon - as always good!
