With the brass version the top is kind of sharp on the edges, also the ink in the cartridge that came with it, doesn't write smoothly and can kind of smear

The ink is still great and the feel of the pen is awesome, but I've had two of these fall apart in a short period of time.

nice brassCONS:~ gets slippery in hand~ doesn't write smooth - ink quality of normal bic pen

Great pen and ink, solid construction, but overall feels slightly thin.

Switched out the medium ink for fine and really enjoy using it for jotting quick notes.

Those NASA features make for an ink pen that does not leak when going through the wash or dryer.

After 2 months, this little pen has become my daily carry pen.-because of the encapsulated design, there is little chance of it leaking on my clothes.-when stowed, it will fit ~sideways~ into the breast pocket of a dress shirt and keep my from looking like a Poindexter, or an accountant, or an accountant named Poindexter.-You get 2 pens in one as you can let it tarnish, or keep it polished to a mirror finish.-I think that a finer point refill will solve my issue of poor ink delivery

One issue is that the ink can sometimes be very inconsistent, and also the pen comes apart very easily

I've had Fisher Space Pens before but it seems they improved the ink

Best travel pens as they are small and have great ink and writing feel
