Title: Great when it works
Review: This pen is comfortable to hold and the ink flows nicely...when it works. I've had this pen well over 2 years now and I've finally gotten so fed up with the cartridges that I don't use it anymore. The refill cartridges mysteriously stop working while there's still plenty of ink left. This is not just a fluke and has happened to me and my husband many, many times.
