Credit where credit is due.
I have had my Lamy Dialog 3 for several years. I like the pen, though its size means that I don't use it all that often. The last time I had used it was a couple of years ago, after which I cleaned it, let it dry and put it back into my pen-case. At that time it worked well and wrote beautifully.
When I tried to ink it up a month or so ago, the mechanism wouldn't work at all - it had essentially frozen and I could't rotate the barrel to extend the nib. It was very strange.
So I packed it up and sent it to Lamy (I presently live in Germany), asking them to have a look at it and let me know how much it would cost to fix. Just over two weeks after posting it, I received a package with my pen in it, which they had fixed and returned to me at no cost.
I have heard that the Dialog now uses a new internal mechanism, so it's possible that there had been a known issue with the old mechanism. Whatever: I now have a fully functional pen again and am very happy. It's really good to see that Lamy stands behind its products.
It's good to be able to share a positive experience.
