    I never had feeding issues so far.

  2. Alexander (verified owner)

    Picked this up so I would always have a pen on me for geocaching without adding too much extra to my pockets. Works great.

  3. Jeffrey A. (verified owner)

    Really awesome. I’ll never again have to say “damn, I wish I had a pen with me.”

  4. Michael H. (verified owner)

    Great little pen to have on hand. Is very sturdy too!

  5. Paul H. (verified owner)

    Good pen.
    Stopper allows it to hold its position against the Keybar frame as you write – nice design touch.
    Would like to see next version allow refills.
