6 Pack - easyFLOW 9000 - Black Ink

very bad quality, fits but doesn't write for more than a few words then dries up

These are lovely Parker-style cartridges. The ink is dark, and rolls smoothly and consistently. They will make for a superior writing experience.

De momento es una delicia, solo he probado uno de los recambios, y tras más de una semana sigue escribiendo como ningún otro de los que he probado en todos los años que llevo usando bolígrafos con este tipo de carga. Ninguna primera marca escribe con ese negro casi puro, con esa suavidad ni con ese trazo continuo... veremos si es así en todos los recambios y cuánto duran, pero hasta ahora, recomendable cien por cien.

Après plusieurs mois passés a la recherche de la recharge parfaites, la quête arrive enfin à son terme ! (Je n'y croyait plus !) Ces recharges ressemble a des billes, sèchent rapidement, ne traversent pas le papier, mais écrivent avec la fluidité des recharges gels. Le meilleur des deux mondes réunit !

The best so far, and the cheapest too!? I went through about a dozen Parker Gel (30525PP) refills, only TWO of which lasted until they ran out. Five (!) of them leaked/exploded at one point or another, and a handful more just quit writing after a very short time. One never worked from day one, and one leaked all over the minute I installed it. I tried the Fisher Space Pen refill, which didn't write very well and stopped working after a short while. I also tried the Itoya AquaRoller Gel 0.7, which ended up being as bad if not worse than the Fisher refills. I'm tired of leaking refills and ruined clothes! I've only been using the Schmitt Easy Flow 9000 for about a month now, but I'm still on the first one, it writes better than any of the others, nice and dark, smooth. Just like you'd expect from a gel. No leaking! (yet). I'll update if anything changes, but I am very pleasantly surprised by the cheapest of the bunch! ___________________________________________ Update August 17th 2016: I'm on my second of the 6 pack now, the first one worked flawlessly until it was empty, and the second is working flawlessly so far too! I just can't believe how much better these are than the more expensive options. They write the best of the bunch too! P.S. I'm a pilot by trade, I use these in my daily flight pen, and the constant air pressure changes must have had an impact on the reliability of the other refills, but these things are just plain rock solid! ___________________________________________ Update August 24th 2019: I just ran out, and promptly ordered more. These things have a very long lifespan, no shortage of ink inside! Every. Single. One. Worked. Flawlessly.
