This is one of my all-time favorite pen barrels. The design is really cool, it's comfortable, and as always with Uni-Ball, it feels really well made. But no matter the amount of superlatives about the design, if it doesn't cut it performance wise I'm not going to be using it. The Uni-Ball Signo Bit is one of the more frustrating pens I own in that aspect.
I want to use this pen so bad, but it never fails that I have to scribble it around a bit just to get the ink flowing. This goes for the 0.18mm (which I have reviewed before in black), as well as the 0.38mm (which I have also reviewed in black). Scratch, scratch, scratch just to get started writing is annoying. Once it gets going it is fine, but even stopping for a short period delays it again.
If you click on either of the picture links you can see how crisp and clean the line is once started, so it is too bad that it causes so much drama out of the gate. I love this shade of pink too. The 0.18mm tip is as fine as it comes in a gel ink pen, so if you need this fine of line and can put up with the occasional dry spot, then this pen is great. And being the true Pen Addict that I am, I have ordered a black 0.28mm Signo Bit to complete the trifecta of frustration.
One final note on the pink: it looks like this color, along with many of the other non-standard colors, are being discontinued by Uni-Ball. JetPens mentioned on their Twitter page yesterday, stating the the Signo Bit will only come in black, blue, red, and orange in all of the tip sizes.
