Pros: Durability, Refill Quality, Materials, Overall Quality
Keep one in the car
I had the misfortune to get rear ended by an inexperienced driver on a snowy, icy day this winter and found myself trying to exchange information and write down info with a frozen (best selling name brand) pen that was in my glove box...FAIL!. I am absolutely positive that if I had a Fisher pen in my car this would have been a non-issue. Fishers will work in sub-zero temperatures (Sub Zero nights in Kyrgyzstan) and extreme heat (125 degree day in Afghanistan and it did not falter, real life experience.). I now carry two in the car just in case.
