Unfortunately, scratching and messy ink flow.

Unlike the black ink Parker to Rollerball pen attaches as pins, this blue refill is unfortunately much scratching and the ink flow is unclean and sporadic. If you write too fast, it feels as if the mine is equal to empty and the typeface is very pale. If you write too slowly, or with short breaks, has significant ink stains repeatedly.

Unfortunately, this experience coincides with many opinions on the internet about these mines, but it is every now and then also provide that the review without any problems, but that speaks absolutely not at all for the quality control of Parker.

Alternatively, I then tried the compatible mines Monteverde times, although these are fine, but they have a decent flow of ink and scratching less.
