For my Lamy pens I wanted to buy a suitable, good quality mine. Many months ago I bought so this cartridge. Since I do not like to review a week after the purchase, here my conclusion for use after a few months:
- At the beginning it wrote relatively normal with the mine. A strong pressing was not necessary to draw clear lines.
- But already another 1-2 months it started with the fact that each new day, or if a few hours went by, and I wanted to start over writing any "ink" came out. So first look for rag and doodle on. Stupid because if you just sit in the meeting or quickly what needs to write down the phone.
- Meanwhile, the fall also write not so easy. The pressure point is now significantly higher, although the mine is likely to be far from empty.
In summary, one can say, see, compared to a low mine and I feel especially no difference that would justify the price.
