1. Appearance and Design: 8
It's a neat little pen, it's not pretty, but it works. The crosshatching and thicker section greatly improves handling over the Speeno. I have been using the Shuangling every day at work to log work orders, and at home to pay bills. I can write with it for extended periods with no discomfort. I use it with a Moleskine log book at work with no feathering or bleed-through.
2. Construction and Quality: 7
The pen is solid, much better built than the Speeno, but the metal sleeve that fits over the filler sac slipped off on both examples. I was able to push both back into place easily, and even if you lost the sleeve, the pen would still fill and write. To be fair, neither sleeve came loose again during the course of the test.
3. Weight and Dimensions: 8
Both pictures show the Shuangling with other popular pens. The pen with the little key hanging off the cap is my Speeno, the bullet shaped silver pen is a Fisher Space Pen. Two Shuanglings are shown, one open and uncapped, the other, closed.
I normally like a heavier pen, but something this small is not going to weigh much, unless it's made of lead. The Shuangling is tiny, but it opens up to a very useful length.
Length closed: 3 3/8 inches, Extended: 4 3/8 inches, Width: 3/8 inch.
4. Nib and Performance: 8
Both pens have smooth nibs and decent flow. The nibs are on the dry side, but had no trouble keeping up when I wrote fast. Parker Quink seemed to perform a little better than the Waterman Blue-Black. Both inks wrote well, but the pens were smoother with Quink. I would say the nibs write a line between fine and x-fine.
5. Filling System and Maintenance: 5
As you can see, this pen is an aero-filler. I marked it down in this category because it's nearly impossible to fill the Shuangling without getting ink on your hands. Because of the size, the nib and barrel threads are close together. The first time I filled it, I nearly drained the sac of ink trying to wipe the threads clean. It gets easier as you practice. Cleaning is no worse than a Parker 51 or 21.
6. Cost and Value: 8
Bob is selling these pens for $16 shipped, twice what the Speeno 1013 cost in 2005, but I think the Shuangling is a better design, and it writes as well as many, much more expensive pens.
7. Conclusion: 44/6= 7.33
I like the Shuangling a lot, it has replaced the Speeno in my left front pants pocket.
Thanks for reading, comments are always welcome.
