I love pens and can be quite fussy. As an Architect I tend to collected them and have drawers full of different pens, to the point I've lost control of the situation. So I was slightly hesitant about buying yet another pen... however, I LOVE it. It has become a default on my desk because unlike the others I don't have issues of ink running out half way and the ink flows beautifully. It is fine enough to perfectly replace a biro for notes and general writing, with a tip that means I can draw legible sketch details too. I now have the Lumos Pro too, which seems to have replaced my entire pen drawer thanks to the different tips. Both are fantastic and I highly recommend. The only thing I still have to work out is the intensity of the ink colour, but so far I have only used the default bottle that is sent with the pen, so I will test other inks to find a deep black.
