When I ran outo of ink for my Zebra and couldn't find a new pen or replacable ink, I stumbled on the 207 and I have to say that I keep this along with my other one in my pocket. Its gel, writes smooth, and doesn't fade. Sure I've had a few problems where it rubbed off because it was a laminated or really super shiny surface but I've learned that if you don't touch it for a minute after you write it comes out fine. I personally try to keep the standard, black, blue, and red on me or close by at all times.
