This pen is basically a slightly more expensive (I got it for $31.50) version of the Safari made out of aluminum. It matches, almost perfectly, the color of my Apple PowerBook G4, which I'm quite happy about.
Compared to what I read about the regular Safari, the Al-Star is noticeably heavy compared to typical ballpoint/roller pens, and my mom's Sheaffer NoNonsense. Sometimes I use it with the cap detached to make it lighter. At that end, the pen is long enough that my hand doesn't touch the cap when writing with it - I have pretty small hands.
The nib size is Extra Fine. I write small, and somebody here told me that Lamy nibs tend to run big, so I got the smallest nib offered. Well, I think this guideline skips over the Safari - this is certainly Extra Fine. In fact, I had to readjust for size because the Sheaffer had me writing slightly larger than normal. It writes fine enough for me to do math with it (writing tiny exponents...not easy). Perhaps a Fine would've been optimal for normal writing, but I can live with this. (Probably saves ink too.) It seems to write somewhat dry, but I don't have much to compare it to.
What I am noticing so far is that the nib appears to be a bit rough and scratchy. Hopefully, this is just a "breaking in" thing that will go away. Even if it didn't, it's not too bad, but not optimal.
The only real problem I've had with it is ink flow. Although the flow is steady while I write - no cutting out - if I leave the pen uncapped for more than 10 seconds (!!!), it stops writing and I have to play with it for a while (sometimes up to a minute) to get it flowing again. The obvious solution is to always cap it, but...ten seconds? If it matters, I didn't clean it before I popped in the first cartridge - but I also don't recall it happening right away. I got it this past Tuesday, and it started yesterday (Wednesday).
Overall, I'm pretty satisfied. It's not perfect, but many of these "issues" can probably be overcome with some time and getting used to it. This ink flow thing is annoying, though. Unfortunately, I don't have a camera so I don't have any pictures or handwriting samples to show. If I ever get a hold of one, I'll add those.
