Writes well. Feel that the price is too steep

A radically different device
I like the variable extreme atmosphere and environment performance, being a SCUBA diver. I would have preferred a small port or grip socket on the pen for security underwater. The cap feels a bit loose. Will test it out thoroughly soon.

Mittlerweile der dritte Space-PEN in der Familie/im Haushalt. Den ersten fand meine Frau schön und praktisch deswegen bekam sie ihn. Ich kaufte mir dann die Version mit dem Touchpadknubbel, den Stift habe ich dummerweise verloren und es musste sofort Ersatz her... Interessanterweise hat der neue Stift eine andere Kappe als Stift Nr.1, wird aber kein Plagiat sein. Die Minen sind top ! Schreiben in jeder Position und auf sehr vielen Untergründen,können temperaturunabhängig ganzjährig im Auto bleiben und schreiben gut, egal ob tiefster Winter oder Hochsommer. Einzig das Strichbild ist nicht so fein bzw. konstant wie bei Parker die unter diesen widrigen Umständen jedoch schon längst aufgeben...

I have the standard bullet pen which is also great, but the shorter, flat cap on the X-Mark is a great feature making it more suitable for carrying in a pocket or attaching to a notebook, with less of the pen protruding out. It's it's long enough when posted to be comfortable to hold and write with. The chrome finish looks great.
