Other comments note how it creates fatigue within an hour of writing, which is also my experience. Whether that's a result of low quality ink holders, tips that force overgripping, weight or something else, I do not know.

I have a pen cup for when I need to jot something quickly and can't be bothered to get my primary pen from another room, and I've noticed that I rarely, if ever, choose the Cristal. Granted, it is far from being the worst pen out there, but I wince at the thought of using it as my daily pen.

Furthermore, I don't think that selling 100 billion copies of a thing is a sign of quality, e.g., see Microsoft's product line.

As for superior design in a similar price category (i.e., get it free at every conference room), hands down, it's the Schneider K15. Solid ink holders, comfortable tip, a nice weight balance (albeit I find it too light overall), with an imo beautiful modernist design as a cherry on top.
