The Jetstream from Uni-ball is one of the best overall rollerballs I have found. With its comfortable and attractive design in black(for 1.0mm) and blue(0.7mm), and the tungsten carbide rolling ball which ensures brilliantly smooth writability, it is a must have. The only fault I can find is the occasional inconsistency of ink flow. Although this can be irritating I stopped noticing it not long after becoming accustom to it.

The Uni-Ball Vision is a plain pen that writes pretty well. It is called the vision because you can see the ink supply, but not that well. There is no special grip and a very thin graphic coat that scrapes off all too easy.

The Uni-Ball Gel RT is available in medium (.7 mm) and micro (.38 mm) widths. It comes in black, blue and red with matching barrels with rubber grip.

The Uni-Ball Vision Elite is a very smooth writing pen with a near executive look at consumer price. The mainly plastic pen has a stainless steel tip with .8mm or .5mm tungsten carbide ball. the .5 has a black barrel while the .8 has a white barrel. The ink sometimes comes out a bit wider than the advertised width.

The Uni-ball Jetstream is the closest to perfect that I have found. The smooth writing is astounding. The only real trouble I've had with this pen is comedy. When most people first see it, they try to twist it until I get tired of laughing and pull the top off for them to use it.

The Pilot Jetstream click pen is the closest to perfect that I have found. The smooth writing is astounding. The only trouble I've had with the .7 mm is when I got to the end of the supply, but one lasts about three months at work, and I write a lot of reports. The 1.0 mm can take a short stroke or two to start writing again, and the writing feels like a regular ball point, though the pen itself still feels great.

The uni-ball 207 is a lightweight pen with a more stylish clip than you might expect on an inexpensive office pen. It writes smoothly, although the gel takes a few seconds to dry on paper and will smudge if you try to write on a line above the line you have just written and make contact with the ink.
