Unfortunately, I have to the - connect less positive review - here to be found already. Also I could not convince the piston converter of Waterman. The converter could be indeed fill any problems with ink, so I was initially pleased so far. Also, the initial letter went smoothly, as I was used to from the original Watermantintenpatronen. After some time, however, the constant exposure of the ink flow became noticeable. Whether you could start a new word or even one point tried to put, there was no more ink in the pen. Only after ansetzte for the second time, the letter was again easily by hand, at least until the next discontinuation of filler threatened. In this state, even comes with a Watermanfüller no joy of writing, so maybe I'll go back to the Watermantintenpatronen.
I can therefore unfortunately no recommendation and had to complain to the piston converter unfortunately.
Summary: two out of five stars (1/5)
Positive arguments: (+ 1 star) - Comfortable refilling the ink - Remarkable savings compared to the replacement of Watermantintenpatronen
Negative arguments: (- 4 stars) - Ink flow irregularly, frequent misfires Useless piston converter systems for the purpose of producing -
