I use since 1988 a Parker Vector Rollerball pen with mines, in the 80 years there has not been a single complaint from me because of any manufacturing defects. Today the product is apparently no longer manufactured in Europe, with the result that the rejection rate is extremely high and the number of complaints at Parker have assumed immense proportions. The main error is obvious in an incorrect positioning of the ball tip in the recording, which the Tintenflußregelung no longer works and a continued exposure to some words used. The tip scratching across the paper without the usual sliding effect, whereby the possibility of writing comfort is completely lost. Only someone who writes correspondingly slowly would therefore have a uniform typeface. This is measured by the price unacceptable! I can therefore only advise everyone to an alternative brand resorting long as the company's technical problems do not come to grips with.
