excellent product it does write in any position as advertised. KT

The pen writes real nice. It has good construction. The only thing I would like to see is some sort of cap for the spike end.

It uses the Fisher space pen refills and the material of the pen itself is outstanding! Love it

Great fit & finish, tough construction. Space pen refills make for an excellent all-condition writing instrument.

Very Impressive all around product!!! Will be recommending to my peers!

Works well for self defense (I tested it against a watermelon and 3 inches of beef) and it writes nice too.

Love it. Not to long, it's comfortable to write with and easy to change ink . The only thing that I would add is a sheath. Like the sheaths that Maglite and Streamlight stylus pro come with.

This is one well-made tool. The fisher space-pen refill was a nice touch.

I fit size large gloves and this tool fits my hands well with just enough projecting out when held in a fist with the cap on; too short without the cap. It is difficult to find a place to carry it though. Clipped in my front pants pocket, it started to wear a hole in my pants. In breast pocket, I worry I'll fall on it and perforate myself. I settled on breast pocket of my service jacket or on my clipboard. It would also work on a utility belt if I wore one.

I like this pen a lot. It is very convenient to carry, so I keep it with me all the time.

Well made tactical pen that also writes very; be aware TSA will confiscate if you are flying but can be stowed in checked luggage..

Excellent product for a low price.
