Review: Worth the hype - Very smooth, nice and inky black pigment, minor bleed through on poor quality paper. The only complaint I have is that the grip area is a bit too wide for my writing style and causes cramps. But for people who prefer a thicker grip, this works really well. Since it uses the same ink refills as the significantly more expensive Signature version, it is too good to pass up. I don't think I will be switching off of this pen any time soon
Review: Smooth black - Smooth. Really. Original uni ball.
