I really loved this pen....
November 27, 2014
I really loved this pen. I loved that you could get refills. I installed my first refill and after a week of use, the pen has gone dry with plenty of ink still in the barrel. The frustrating thing about these small purchases is that it is REALLY inconvenient. Of course I did not think to get two. Why, when the first pen lasted a long time? But what if I did and faced with two duds? The inconvenience factor ratchets up the loss in trust in the product, never wanting to use it again.
