At first glance, the cook makes a solid impression and noble, but unfortunately evident in the operation but the moderate processing. Again and again, water vapor escapes through the thread, so that the pressure inside never reached the level to make the stove work as planned. The coffee has been slow and is thus bitter. Once I succeeded, the pot so strengthens firmly turn (and there must not be squeamish and you use so much force until the pot threatens to bend) that the stove was really close and led to the desired result. In the end, however, remains the riddle of how to get to all four espressos. A coffee cup is only half full.
Since I bought the cooker mainly for camping, I can overlook this deficiency, for a good Sunday Espresso it is sufficient but not far.
