Personally I find the Uni-Ball Vision Elite overrated, and favour the simpler and more understated Uni-Ball Eye over it. They're also better to chew on.
Have been using uni-ball eye for over 10y. As a left handed, this is the best pen I have ever used. Many other pens "scratch" on the paper or result in inconsistent line thicknesses.
Writing with this is a pleasure. Also dries quickly enough on normal paper.
Yup, they're great. At work they've become almost legendary. Usually one can only find bic pens and the like, but occasionally these make their way to a cupboard somewhere and once word gets out it is immediately raided. I even bought green (colour not found in the office) ones once with my own money just to be able to swagger off with. Very well spent money indeed.
Airplane cabin safety can mean a lot if you travel that way. I also find the broader Vision Elite 0.8mm doesn't collect ink around the rollerball, as the Vision/Eye 0.7mm does.
Nothing wrong with the classic Vision/Eye pen. Or Pilot's V5 or V7, for that matter.
