This device makes a good coffee, lean, rich in aroma and no bitterness. I use the Aero press with the supplied paper filters that I use repeatedly. The coffee beans are ground directly in front of the preparation with a Hario MSS-1B Mini Mill Slim Coffee Grinder. Ommm! I start the kettle before grinding, so that the water has about 85 ° C during brewing.
I highly recommend buying this device unconditionally.
