I work in the automotive field and constantly writing in the office and outside in the lot. I found that the Uni-Ball Jetstream pen has been my favorite for every part of my job.
Working in the office I am in touch with many sales associates, managers and customers, so I like a pen that looks professional, writes classy and a pen that if it is misplaced/taken, you know it did not cost you a fortune (like Mont Blanc'S) . I like the chrome looking accents which makes it look elegant, yet I did not break the bank paying for. It is costly if you consider it a disposable pen. I consider it my Mont Blanc. I personally like the black 0.7mm ink, again, it just looks more professional. The pen has gel ink and glides across the paper and dries immediately, therefore, there is no clumping and your hand does not drag ink across the paper or have ink left on your palm.
Working outside, the weather can be cold, wet, hot or dry, yet the pen does not disappoint me (although, you can not write upside down or upright for too long) it will continue to write. I prefer the click top because you can easily loose caps. I have lost many caps in my time resulting in writing on the customer car leather (bad) or all over my clothes.
Whether inside or outside it has proven to be comfortable with its soft rubbery writing barrell and the pen lasts quite a long time, as long as it is not stolen from my desk! But refills are available for this pen to be cost and Green efficient! I am the envy of the office and many of my pens have disappeared because of the quality and looks of the Uni-Ball Jetstream pen! I recommend this pen for work, school or home!
