The only drawback: the scale filter, but it bothers me at all water containers and can be upgraded. Who his maker so long does not clean that out Kalkstückchen crumble, this has also kindly mitzutrinken. ;-)
Among the negative aspects of the other reviews (which I do not share):
After I have spilled some on the first pouring me the trick was also quickly became clear: you have to stop pouring more slowly. But then it is "highly accurate", are also found easily in hot-water bottles. This also explains the different ratings: he that is hasty saves while pouring, but needs to spill accordingly more time, everything aufzuputzen again. However, you can easily fill a large cup of coffee in 2-3 seconds, not only in 1 second.
The fixed cover is the best in my eyes, what you can have, it is for safety (against spilling during boiling and transport). The marking "Max" can be seen well; However, one needs to have some light from above. In poor lighting from the side that is not so easy.
