on saleNoodler's Ahab Flex Fountain Pen - Clear

Love using it with no cartridges or converter, huge amount of ink, love being able to see amount of ink left in the pen, love the flex nib, in short, there's nothing not to love about this fountain pen.

The nib was to far out letting to much ink come out. I pushed it in and it helped. I am also going to heat set it some time in the near future

This is not a fountain pen you just put ink into and start using. I will go through the steps to set up this pen.
1: Disassemble the pen. Be careful with the breather tube, you don’t want to lose that.
2: In a warm bowl of water put the feed and nib to soak. Get an old toothbrush, a good degreasing dish detergent like Dawn and get a brass shim to “floss” the nib. A .025 metal feeler gauge blade will work also.
3: Scrub the nib and feed thoroughly with the toothbrush using the soap and warm water. Scrub the shim or feeler gauge blade to remove oils then “floss” the nib while it’s in the bowl. The idea is to remove any and all oils from the manufacturing process.
4: Dry everything off and reassemble the pen. Push down the piston on the pump converter to make inserting the breather tube easier.
5: Make sure 8-10 ribs of the feed are exposed from the end of the grip section. Usually 9 ribs is about good place to start.
6: Once the nib and feed are seated correctly (there’s a notch the nib goes into). Fill the pen by submerging the nib & feed and a bit of the grip section into your ink. Pump the piston converter a couple of times till the converter is completely full.
7: Test the pen. If it writes too wet, push the feed in 1 rib. Test the pen. If it still writes too wet. Push the feed in another rib. You should find the sweet spot where the pen writes the way you like. If the pen initially writes too dry, pull the feed out one rib. Continue this procedure till you find your “sweet spot”.
The same steps work for every Noodler’s pen. Though the number of ribs showing might be different from model to model.
There is nothing wrong with Noodler’s pens. I use them for my artwork exclusively. I often carry a Nib Creeper as a vest pocket/shirt pocket pen. They are inexpensive, robust, pens that perform gloriously when tuned. They can be fitted with a multitude of nibs of different types. The bonus are the refillable .308 cartridges. They give the Ahab, Triple Tail and Neponset a huge ink capacity without resorting to eyedroppering the pen. So no ink burping from hand heat. I have 10 Ahab, 9 Konrad, 8 Nib Creeper and a Triple Tail. All of them have been tuned to perform as well or if not better than any TSWBI, Pilot, Kaweco, Platinum, Pen BBS, Jinhao, Asvine, etc… pen I own.

La verdad es que es dif�cil encontrar plumas con plumin Flex fabricadas al efecto y esta es una de ellas que cubre todas las expectativas a un precio muy asequible. Una maravilla

That this is not a very good pen. I've experienced similar problems to other people here. Odd smell for the feed mechanism, it eventually went away after a few weeks, but at first it made writing with the pen impossible. And the feed wasn't fast enough, I would write half a page and then have to wait 10 minutes for it to "re-ink". I would suggest the TWSBI go as an intro piston fountain pen instead.
