Once again only rip

I use the pen for years every now and again, because the notes look much neater by the etching, as with a standard ballpoint pen.
To my regret, the life of the cartridges in recent years but declined significantly. This is typical of a company that has a lot of success with his product, and new sources looking to make more money.

If the cartridge you look at the new state, you will notice easily that they are already half empty there. Since the service life can not be great, for the benefit of the group, because then you have to buy so often new, much too expensive cartridges ....
I have to start 3 times new cartridges in the last 4 weeks, and am now that I probably need some variety in the manufacturer, in order to regain a decent product with good quality so disappointed ..
