The small pressure lever on the lid of the pot breaks off quickly. On the one hand he is the only stop when you up the lid and unscrewing, secondly, it breaks off even with normal use. The last time only a half pot of coffee was needed. The air in the half-filled pot heated up, possibly transported by carry the jug (smooth adjustment), pressure built up, and when you try the first cup of coffee to pour "crack" - was from the pressure lever. In addition, the related hard plastic lever structure is brittle and breaks after a few months, almost by itself.
Without this lever, you have to unscrew the entire cover every time for a cup all. Since the lid has a smooth surface, you can also find little support to apply the force up to him and screw it again.
We had to replace all the cans and have in 2 years have to replace a total of 11 pitchers in this way. Annoyingly, it's cheaper to buy a new pot, reorder as a single cover at Bartscher. In addition, the manufacturer has seen so far compelled, in any, to solve the known problem with the lever construction in the lid.
Too bad.
