  Amazing pen, great flow..., December 19, 2010
Amazing pen, great flow and consistency. Didn't skip. It's not the nicest looking pen but overall it's still nice to write with.

Excellent pen for note taking! nice, controlled and THIN lines, good size barrel, does not scratch onto paper, etc. This is my favorite pen for note taking for long periods!

This thing feels like heaving when writing on paper. it's soooo soft and precise. I use this pen and the jetstream I have and prefer this over the Jetstream. If you are trying to find out which pen fits you best, definitely give this one a shot!
  WOW!!! I have given up..., February 26, 2009
WOW!!! I have given up on all other pens (including fountain pens) because of this simple yet amazing gel writer. The barrel is nice and long with a slightly enlarged grip area that fits my hand perfectly. The ink is just amazing with a super smooth feel and a dark vibrant color. If you have a cursive hand this pen is for you!

Awesome Jel pen. Very very smooth and can write without putting a lot of pressure on it. This is quickly becoming my favourite type of gel pen.

this is my favorite gel pen. the barrel is nice and sturdy, and the octagonal shape helps keep the pen from slipping/rotating while you write. the ink comes out super smooth, even when there is only a little ink left...this pen ink has yet to skip on me. the ink itself lasts for a good amount of time; i started a new one to write 200 thank you cards with and am STILL using the same pen. amazing!

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.8 mm - Silver
Excellent silver ink pen. I just picked up a large sampling of different brands of metallic pens on Jetpens to find the best one, and I think Uni Signo UM-100 is my favorite! (I just wish the gold UM-100 would come back in stock because I reallyreallyreally want to try it too!)

Signo UM-100 silver is almost like a paint pen (without the paint pen smell) because the ink is so opaque, shiny, and pretty, and the pen writes soooo smoothly, I wish I could write everything in silver ink.

Like another reviewer said, I didn't expect it to work so well on light paper (because most silver pens don't show up on white) but the UM-100 silver shows up just perfectly on both light and dark paper.

I'll definitely order 2 or 3 more Signo UM-100 silver pens...just as soon as the gold UM-100 is restocked, hint, hint! ;-)

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.8 mm - Silver
This pen is AMAZING on black paper. I definitely recommend this. On white paper it is kind of hard to see, but that's for all silver pens. The ink flows very freely, and is really vibrant. I will most certainly buy this again.

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 12 Color Set
These pens perform super well. The ink flows beautifully without skipping. However, my only gripe is that the colours available are ugly. If they could combine the colour selection of the Hi Tec C pens with the quality of the UM-100's mechanics, it'd be a match made in heaven!

  Great value for what..., October 28, 2009
This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm - Black
Great value for what you're getting. Very smooth, very nice. I'd be using these instead of the DX if they had this in 0.38. I actually prefer the pen without the rubber grip, since it makes the pen look more minimal. Often borrowed, rarely returned. Get more than one.

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm - Red
When they work, they work great but ink flow can be iffy. Most of the time tapping it straight down on a scratch pad several times gets it going again. Also, have to give ink 2 or 3 seconds to dry before touching.

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 12 Color Set
I love these pens! Writing with UM-100 (0.7mm) is smooth and free of skipping or scratching. None of the colors in this 12 color set are opaque, But, OH how I WISH THEY WERE!!!
In this set, the fluorescent red is (I think) the only color that JetPens does not sell seperately. And I actually purchased the 12 color set JUST for that pen!
Also, the case is just soft plastic/vinyl but is very sturdy, able to survive being crammed into a bookbag with many heavy books. I'd purchase this set again for sure.

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.7 mm - Light Blue
Not your average light blue pen.... Finally, light blue ink that you can see! I usually steer away from light blue pens AND 0.7 mm pens. The color is usually too light to read easily. And writing with a 0.7 mm gel pen typically reminds me of driving a car with sloppy 1970s power steering. You try to aim for where you're going, but it's anybody's guess where you'll end up. This isn't a sports pen, but it goes where you aim it, and it looks good getting there.

The fluorescent color sometimes have like a the color doesn't completely fill what you're writing look, but I can't exactly explain it or I don't know what the word for it is. I like the color though.

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm - Red
RED RED AND RED. This is a great pen for 0.5 mm. It doesn't smear if you give it like 4 seconds or so. Smoothness wise I think it's not ubber (yes, I said ubber) smooth and the flow of ink is good/okay, but not the best. The barrel is very simple plastic barrel. This pen is a pen worth buying thought.(:

This review is from Uni-ball Signo UM-100 Gel Ink Pen - 8 Color Set
HMM! This set of gel pens did not disappoint.! I am very satisfied with them. They write well and the color is good too! For gel pens they don't smear if you give it like 3 seconds and if you press hard on them there is like not a filled in line or so. I can't explain it, but if you don't write hard it looks super good. (: BUT IT! YEAH.!
