I think this is the first pen I've tried from Uni-ball where I think they dropped the ball. In the past, I've reviewed several Uni-ball pens and I've loved them all (my favorites: Vision Exact, Signo DX, Signo RT 0.38, Scented, and Signo RT 0.7).
The ink is pretty decent overall: it dries quickly, doesn't smudge or smear, and doesn't bleed through, even on this thin sugarcane paper. The ink is a decent color. The black is solid and deep, the blue is solid and classic. As I mention in the writing sample, the problem comes with the ink. I suspect it may be from the shape of the tip. When the pen is straight up and down, the line comes out smooth and thick (0.8 mm) and wet. If it's at an angle, the line peters out and skips. In the case of the black pen, it didn't even write. This inconsistency is unlike Uni-ball's usual quality. Overall, the ink flow feels very dry and skippy and is not what I'd want in a reliable, dependable pen!
I'm not the only one...

I'm hesitant to recommend this to others. At this price, there are other options that I think are way better. The Uni-ball Vision RT is not particularly unique in any way, except for its appearance. Given that the ink is Super ink, perhaps this pen can be utilized for signing checks and documents, but I wouldn't give it much more thought than that.
