Hey - I posted this thread a month ago. Got a couple responses (which are above) but nobody seemed to have made the pen at the time.
Well, a month has passed. I was on the "wait list" and ordered when I got the notification PSI had them. I got 5 and made them this weekend. Pics will follow, probably tomorrow, but I'm writing to post a semi-review.
The pen is pretty good, but flawed IMHO. It is VERY similar to the CSUSA Manhattan. The click mechanism appears the same as the Manhattan as does the clip and the method it is attached to the body. Both use a Parker refill and the bushings are nearly identical (Manhattan's 0.471" vs Vesper's 0.474"). The Manhattan specs a 13/32" drill, the Vesper calls for a 10mm which is a slight difference.
The rest of the story is basic - assembly is straight forward and goes well. The instructions are ok.
The issue is with the uniqueness of the pen. Its design is a click ballpoint where the refill advances through the center of a stylus. When retracted, the stylus is available. When advanced, the pen is a standard (and comfortable) ballpoint. But on the 5 that I made, the action of the stylus sucks. I tried it on my iPhone. No good. Same for my iPad. Tried my wife's iPhone and tablet with the same results. Same as well for my brother-in-law's non-Apple phone. I took off the screen protector on my iPhone and the action improved a little but was still poor.
Needless to say I am disappointed. Going to CALL Penn State tomorrow and see if they have a resolution. Will post their reply tomorrow (with pics).
