Well, the pen arrived today just before I left for work. Opened it tonight, when I got home to do an initial check - out!
First impression was very positive with the blue acrylic and rose gold furniture. Nice presentation as well - different from the somewhat bland one with the black Duraflex from Goulet. (Quick aside - the presentation of this one was what the other one SHOULD have been - IMHO).
Anyway, did a quick dip test using Diamine Sapphire Blue and wrote with it. A little feedback and a little line variation. After loading the (screw-in) converter I wrote a few lines and applied some more pressure. Nothing sprang or disassembled that I experienced. At least not so far!
This is NOT anywhere near a vintage flex nib, also imho.Nor did I expet it to be. It offers some line variation and may deliver more with additional use and "loosening up" over time. I may do a more complete review if there seems to be enough interest.
One thing additional. One of the reasons that the pen caught my attention was that it reminded me of the blue Aurora Optima "Auraloid(?)" that I owned sometime ago. In hand, the color is not as distinctive or bright although still quite nice. I do expect to put this pen into my somewhat regular rotation to determine its longer term durability and performance. One thing that I may encounter (as I have with my Goulet Duraflex) is that will longer writing periods the converter needs to be advanced to keep the feed "under pressure" and providing the supply of ink needed for extended periods of line variation writing.
Unless something happens to change my current positive experience with this pen, it's a Keeper in my pen larder.
