A Sales Representative from the Pilot Pen Corporation met my Wife Chris at a vendor's fair. They are introducing a new line of whiteboard dry erase marker so my wonderful wife showed the Rep some pictures of my dry erase murals. What do ya know, Pilot just sent me a bunch of the new pens and asked me to evaluate them. I guess they think I'm qualified. So far they are great pens however, they are very limited in color choices (only black, red, blue, green, orange). Also, they seem to suffer the same problem as their competition - when you are writing on a vertical surface like a whiteboard, the pen is angled up so gravity works against you on the ink and the tip dries out.
