Pilot CON-50 Piston Converter is rated 4.5833 out of 5 by 108.
Rated 5 out of 5 by from Much Easier I bought a Pilot metropolitan a few months ago, and while I liked it a lot I didn't really love the bladder converter. It was difficult to tell when I'd really gotten it full, and impossible to know how much ink was left. I picked up the CON-50 converter and it alleviated both problems completely. The CON-50 is super simple to use, and is clear so you can see generally how much ink is left. No guess work involved. The CON-50 technically has a lower ink capacity than the bladder converter, but I think that's completely mitigated by the fact that you'll more reliably be able to fill the CON-50 to capacity, and with confidence.

Rated 4 out of 5 by from Looks weird, works fine The Pilot CON-50 converter looks a little strange. My Waterman, Parker, and Visconti piston converters all look roughly the same: they all taper near the end that connects to the pen's feed section. Not so with the Pilot converter: it just has a gaping hole at one end, that is pushed into the feed section of the pen and draws vacuum (or so I guess). It works just fine, though: no excess ink flows out or anything. Nevertheless, I have had two accidents with this converter in my Namiki Falcon, where a copious amount of ink flowed from the nib and feed all over my hands. Don't know whether that was caused by the converter, though: I may simply have been twirling the pen a little too much :-)...

Rated 5 out of 5 by from The New, Excellent Pilot CON-50-Banzai (hooray)! The new converter design with the 'weight' is superior to the original piston converter which had problems. With the old design, ink would often get stuck up at the wrong end of the converter and ink flow was affected. Now, with the help of the small, cylindrical weight, gravity will, generally, pull the ink down towards the feed nipple when a Pilot pen is moved into the writing position. Montblanc also modified its converters in this way several years ago. The weight makes up for a flow problem that often occurs with converters that inhibit the intended exchange between air and ink (L. Waterman realized this need). Many converters are not designed or made correctly and extra air leaks into a converter throwing off the special balance between ink going out and air coming in to replace the ink. If the ink doesn't move back and forth in the converter the way water moves back and forth in a carpenter's level, something is wrong! The new CON-50 helps make up for a converter deficit.

Rated 5 out of 5 by from Works great Sure, the Pilot CON-50 does have a small ink capacity, but it's comparable in size to most other converters out there, so I can't really fault it for that. The construction feels sturdy, and the piston moves very smoothly. A surprise to me, when so many other twist converters need more coaxing to move. The little agitator in the converter gets a bad rap. It might lower the ink capacity slightly, but I'll take it if it means less flow issues. I've also never noticed it rattling around at all unless I'm purposely moving the pen the hear it.

Rated 4 out of 5 by from About time!/Pilot CON-50 Piston Converter For all the convenience of Pilot's Vanishing Point pens, they are notorious for their small ink capacity when using thew converter. Given than the standard Pilot converter is not the most efficient sucker-up of ink, you can find yourself running dry at inconvenient moments. Pilot cartridges hold lots more ink, but I don't like cartridges. The CON-50 converter is a reasonable solution. I don't suppose it is any more efficient at sucking up ink, but its larger capacity will provide a noticeable improvement in the amount of writing you can do on each refill. (TO NOTE: the "Stealth" Vanishing Point seems to ship with the CON-50 as standard. You should not need to order this converter.)

Rated 4 out of 5 by from must have for Pilot Parallel Pens the converters are a nice addition to the Pilot Parallel pens, in case you like to use bottled (fountain pen) ink. Easy to use, and convenient. The clicking sound of the metal thing, makes you want to shake the pen, which may not be advisable. Depending on the color of the wallpaper at your friends place, or the desk of your boss,

Rated 5 out of 5 by from Easy to fill I am new to fountain pens but found this converter to be super easy to use. The agitator is not a problem at all and I can't hear it unless I shake the pen roughly, which given that I am not in the habit of violently shaking pens, isn't a problem. It holds a good amount of ink and can be filled quickly (I have filled it and cleaned up in less than five minutes when running out the door.)

Rated 1 out of 5 by from I hate this converter This converter is small enough to fit in a Namiki Vanishing Point, but the small size renders it nearly useless in my opinion. I far prefer refilling Pilot cartridges which is the one saving grace of that pen -- the cartridge design allows for very easy refilling. It is interesting to note that after ages of complaints about ink sticking to the walls of this converter and not going down to the feed, Pilot has innovated by adding an object that will break the surface tension of the ink to the converter. I appreciate the effort, but it isn't enough to turn this into a viable converter in my mind. Some people indicate the CON-20 is a better option and that it will fit the Vanishing Point. I will one day soon try it to see if it is any better.
