I have long possessed the 2-cup version and am very happy with the unit and has so far always prepare excellent coffee.
+ Stainless steel (no ill aluminum)
+ Simple & pretty
+ Works fine also on induction stoves
+ Close
- Cover built somewhat impractical, if you take the pot off the stove and pours the same, you have to watch something on the steam, but is not so tragic.
For those who are wondering perhaps how much milliliters of coffee you can prepare so that when you fill the water up under the valve, as it says in the description, fit 200 ml of water into the ground vessel, thus it is probably more than 120 get ml coffee.
The diameter of the bottom surface is 9.6cm
