My first fountain pen was the Kaweco Sport. I loved the compact style and the ability to throw it in my pocket and not worry about it leaking.Last year, I was starting a new phase in life and thought I would commemorate it with a nicer pen, found this one and it fit the bill nicely. It wrote smoothly, was balanced, looked classy, and had some heft while keeping the compact size and the security to carry it the same as my favorite Kaweco.While my pen collection grew, I kept this one as my daily driver and it never left my notebook. From the beginning I noticed that when I would twist off the cap it would slightly open the ink chamber as well, I thought it was user error, but it kept occurring.Last month I contacted the company to see if there was a quick fix to keep this from happening. With in 10 minutes, a representative contacted me back, diagnosed the issue and started the process of sending me a new pen. My new one works perfectly and has no signs of the same issue.I love the pen, but this company has done even better standing behind their products.Additional Thoughts:In the pen forums, I have seen many saying that this is just a repackaged and marked up cheap pen and to just get the Hongdian at half the price. While they are similar, they are completely different. I do like the rubber ring at one of the threads to keep it better sealed, but otherwise, the EDC is a much petter pen.This became clear when I accidentally washed a Hongdian in my pocket the other day and when I pulled the it out, my hand was covered in ink. Water was dripping from the finial and when I opened it up and blew into the cap, I found out it was not air tight. I tried this on my Scriveners and they didn't budge a bit. I feel much more comfortable carrying these on a daily basis.
