I had a Level L5 with a M nib and I had nothing but problems keeping it flowing well. I sold it.
OTOH, I've got a green M Level L65 at my desk that has been filled for about 3 years with no issues whatsoever. It's never been flushed. When I pick it up, it never ceases to write at once. Almost a perfect pen. Holds a ton of ink. But....there's a trick and a catch. I store the pen upside down on my desk, standing on it's flat, flared cap. The L5 has rounded cap and can't do this. The L65 seems to love being stored upside down like this, as it keeps the feed wet. The catch with the pen? Changing inks is a PITA, and totally not practical.
I agree with Richard in general: "Whats' the point?" It's definitely over-engineered, very Teutonic. If I was a person that carried one pen and didn't mind using Pelikan black or blue, then it would probably be great. But being the anal retentive guy that I am, I HAVE to have 10-15 pens inked up any one time and it's rare that I write one dry. I love the filling, changing inks, looking for something different aspect of this hobby too much to only have one pen with one ink!

I've worked on a couple of them, and I guess the big question I have is... WHY?
It looks cool, and it writes, but filling it is a pain, flushing it is a pain, working on it is a pain, and I really do not understand the point. Pens are supposed to be convenient.
Somebody was selling L5's on FPN or PenTrace for 20 GBP this week.
No, they've been discontinued for a while. What I am surprised at is that the L5's retailed at $275, which is ludicrous!

I also have a Level 5 that I got several years ago. I like the pen a lot as I can fill it once and write with it for almost a month before the ink runs out. The pen I have has a fine point that is quite smooth and responsive. I have to agree with those who wonder why the pen was made the way it is; what was Pelikan thinking? However, leaving that aside I've never had any problems with mine and use it on a regular basis. I find that it's well-balanced and very comfortable to write with for extended periods of time. If I could get another one at a reasonable price I'd probably buy it.
I always wondered how it disassembled so I'm happy to see that was discussed here. Now I'll probably go try it and mess up the pen, but it probably does need some cleaning after almost ten years of use. Is it possible to flush the pen without taking it apart? I was under the impression that these pens had been discontinued by Pelikan are they still in production?
