I used it in the Uni Ball Signo DX & don't even need scotch tap.

This is an example of an even further improvement to an already-existing great product. The first two Machs were wonderful pens themselves. Yes, maybe wrote a tad thick on certain papers with some ink spread on the steno pad I generally use, but now this model eliminates any unwanted line thickness. The result on paper appears like a gel pen. And with a nice spacy modern look. Those Koreans really know what they're doing. Pilot and Uniball have no match! Nice work.

Yeah, I hack it into other pens too. For some reason, it's better than the traditional hi-tec C but too small/short so I just get some scotch tape, extend the refills and put them into just about any other pen (I've done Pilot G6s, Bic Velocity, etc.) You learn to use your ingenuity.
