Awesome and easy to use
These little guys hold a good amount of ink and work like a charm, so much easier to use than a regular syringe. I can now refill my pens with one hand. I'll be purchasing these again, for sure.

excellant quality and easily swappable with other pens.
I have purchased several of these and they work extremely well with being able to re-ink fountain pens. Thanks for making these available.

Simple yet outstanding!
Quite simple yet truly outstanding. Great value. Good build quality on both the metal and plastic parts. Quite durable. I have used mine for over 2 years. Very easy to assemble for use and disassemble for cleaning and drying (as shown on the video). I was so happy and impressed that over these 2 years I have gifted several of these along with fountain pens when I gifted them to friends and family. My only knock and the reason I gave them 4 stars instead of 5, is the chamber capacity and the inability to fully fill the whole chamber of the syringe.

Makes refills so much easier
Works flawlessly when you know what you're doing. Be careful to not put the needle too far into the reservoir if you're choosing to refill the ink reservoir inside the pen due to it being hard to avoid overflow. But it's fast and easy to use. Definitely recommend!

NOT a Good Convertor!
Was really disappointed to see this fit absolutely ZERO of my pens as a standard convertor. If you use Lamy, Cross, Parker, Kaweco, or Rotring pens, there's a good chance you're outta luck in terms of using this as a convertor. And, since you can't use this as a convertor... mostly... ink capacity is just about as useless a measure as the Potrzebie. The design is fine, but cheaply made; expect that little red cap at the top of the spring to just fly off, rendering at least one of your syringes useless. It's a cheap Chinese tube. If you expect it to be some luxurious feeling item, you're a fool. Would I buy again? Probably not. But if you refill cartridges yourself, I can see the value proposition.

Works - No Instructions Included
Wish it came with instructions although it’s fairly intuitive, would be nice to have a confirmation other than the photos on Amazon. How it performed well.
