June 23, 2012
I love very fine point pens. I have had a lot of trouble finding truly good
ones. That is until visiting a friends house and picking up a pen to write down
some information. The only word that comes to mind is WOW! A gel pen that
won't run, won't smear, yet is a smooth writing instrument. I had to order my
own set.
If you like a wide range of brilliant colors, a fine tip, an all around great
writing experience order these. You won't be disappointed.
Oh, and the speed of shipping, excellent. The packaging-excellent. (I live in
an area that usually takes longer than most to receive anything.)
I will be ordering more, to complete my colors.

January 15, 2012
I was in English class and I found one of these pens on the floor. I liked how
clean the lines wrote and how I didn't have to press hard on the paper in order
to keep consistency with my words. These pens were so great that I specifically
searched them up and bam, the order came in a few days later. If you don't order
these you're totez missing out.

November 10, 2011
I actually spent all of last weekend looking for some good pens to replace my
G-2 pens which I currently (well, now it's previously) use. And I must say,
these pens are great!!! I bought these pens in the 10 piece set in .38 mm and I
love them so far. The quality of these pens are great and are superior to that
of the G-2s. For note of reference, the G-2s I had had a 1.0 mm head thickness.
And man, what a difference does pen head thickness make. I can now draw
intricately and delicately as well as being able to write much much smaller. I
would recommend these pens to anybody who values quality pens.
On a side note , I also bought 1 Pentel Slicci and 1 Pilot Hi-Tec-C in .3 mm
each just to test them out. Even those pens produced much finer lines, but these
pens did not have plastic grips on them. I think the next time I order these
pens I will get them in .28 mm thickness. No complaint about these pens, guys,
definitely worth the $!

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Lavender Black
I think I'm in love with this pen. I'm a huge fan of the .25mm Slicci, and this
pen--this color in particular--gives it a run for its money. Ink flow is smooth,
pen is well-balanced, and the color is phenomenal. You know how a lot of purple
pens end up looking kind of fuchsia-ish? This pen, on the other hand, is a true,
deep, royal purple. I adore it. I also got the Black, Bordeaux Black, and Brown
Black, and I love them all for the same reasons (although the lavender black is
my favorite color). There is a noticeable difference between this .38mm line and
the Slicci's .25mm line, so I won't be using this one for extreme detail work,
but there's nothing wrong with having different instruments for different
purposes. Excellent pen!

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Green Black
I love this pen. It writes smoothly, and the ink is a deep, pine green that
looks great no matter where I've used the pen. The color is subtle (it doesn't
scream "I'm GREEN!") but still looks unique.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Blue Black
I find the 0.38 mm version to be a sweet spot of fine, concise lines and ease of
writing. The blue black ink is a fantastic alternative to the usual black but
still professional in appearance to be used in a business setting.

This is a very bright pink! Almost like a hot pink. I like the 0.28 Uni pens. I
think these are quickly becoming one of my favorites.

May 21, 2012
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Blue Black
This is the sweet spot. The .38mm is not too thing or too bold. I found .4 to
be too thick and .3 to be too thin. 0.38mm seems to be the sweet spot.
Also, as far as the color, its just the right amount of blue where it doesn't
hurt your eyes but its enough blue to distinquish it from black.
Its the best!

November 11, 2010
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Bordeaux Black
I LOVE this pen, and all the DX UM-151s. I teach at the U of Utah, and this is
the pen I use to grade all of my student's papers. The tip is fine enough that I
can make little corrections in the margins and between lines; the "Bordeaux
Black" color is red enough to seem like it's chastising my students for their
silly mistakes, but not so red that they feel violated (turns out that bright
red pens have a negative effect on students); and the smoothness is unlike any
other pen with a tip this fine. The "blotchiness" that another reviewer
mentioned is, for me, more like a fountain pen's "flair" once you get more used
to it (perfect for writing kanji). Finally, one of the greatest features about
this gel pen compared to every other gel pen I've used is the speed at which it
dries--it's a smooth, fine gel ink that won't smudge. Awesome, awesome pen. Also
great for writing in the margins of books.

September 12, 2010
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Blue Black
This pen has a stronger tip and better ink than others. I've tried the Hybrid
Technica and Hi-Tec-C pens and I disliked how fragile their tips were, you feel
like you're going to break it if you write too fast. In addition, the ink from
this pen dries significantly faster than the others', which is really nice if
you're going to be writing on a semi-glossy surface like taking notes in a
textbook, writing a card, or writing left-handed. After I tried this pen, I
never bothered trying another manufacturer's again.

this pen is a disappointment....,
January 23, 2010
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Pink
this pen is a disappointment. the ink flow is great but it's so scratchy. i
can't bear to use it, almost feels like nails across a blackboard. i've used
uniball signo bit 0.18 and that was not scratchy at all so I have trouble
blaming the scratchiness on the pen being 0.28. i do find the tip very durable
and the barrel size is very comfortable.
it would have definitely been my go to pen for taking important class notes
since it's waterproof and coffee/water spills are way too a frequent occurrence
on my desk but the scratchiness of it is unbearable.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Pink
this color isn't as pretty as in the picture; it's almost maraschino
cherry-colored. i'm kinda disappointed by the ink flow, especially b/c it's .28,
sometimes i have to write over what i've written a couple times for it to show
up. definitely wish i'd gone with a .38 of this pen in a different pink.

August 1, 2012
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Brown Black
I write incredibly small and the DX in Brown Black (0.38 and 0.28) is my
signature pen. I've tried Hi Tec Cs (in 0.25, 0.3 and 0.4), Pentel Sliccis (in
0.25 and 0.3), and Zebra Sarasas (0.4). Each is a very different writing
experience and each have their strengths. For every day writing, though, my
heart belongs to Signo DX.
The tip is very strong; some say it's scratchy, but that makes me think of an
unpleasant sensation. Instead, I'd say it definitely feels firm and precise (but
not grating). Unlike Hi Tec Cs, they don't need to be "primed" by scribbling a
bunch before the ink flows evenly. The brown-black ink is gorgeous; it's dark
enough that it doesn't look gimmicky or childish (though I love those as well
:D) but just brown enough that it looks subtly different and has a rich warmth
to it.

May 17, 2012
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Brown Black
I want to disagree with the reviewer that says this color is not dark enough to
use for business. I use this pen anywhere I would use a black, or blue-black
pen and am quite happy with it. It is especially nice to use if there are
several people writing on the same papers, and you can identify your own writing
by color. It is not quite as distinctive as blue-black in my opinion, but just
subtle enough that few people will notice it unless they know to look for it.
Also, I'd like to say that I find the 0.28 and 0.38 pens last much longer than
the 0.5 size pens. It's quite noticeable to me. I prefer the 0.38 size
overall. The 0.28 can be hard to read for some people depending on the lights
or their eyesight, and I avoid the 0.5 just because it runs the ink out too
fast.
Great pen!

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Violet
I'm glad I gave these 0.28mm pens a try. They are an everyday use pen for me, I
bought all the colors in 0.28 & 0.38 mm.
Hint to like-minded pen collectors, this violet color is the only one that must
be purchased seperately, because it is not included in any of the color sets.

January 25, 2012
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Green Black
Love this pen, it is quickly becoming my favorite. Writes rather fluidly for a
0.38 mm point. In fact, I am extremely impressed with how small I am able to
write, without skipping or any problem whatsoever. It reminds me of fine writing
instruments I used as a draftsperson many years ago. The green-black ink is a
wonderful color, more of a pine green. I love writing with it so much that I
plan to order more in different colors to use for both writing & drawing. At
this price I can afford to indulge. Thanks JetPens.

This pen is fantastic....,
September 26, 2011
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Blue Black
This pen is fantastic. Due to a previous person's review stating that the pen
was too scratchy I bought this .28 size and the .38 size. While the pen does
have a scratchy quality due to the small size I found that I acually liked the
drag on the paper and that my handwriting was far more legible.
The black - blue color ink is a great mix of the two colors, that also looks
unique.
The pen ink lasted a lot longer than I had expected, and that was with daily all
day use. I will definitely be buying this pen again.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Black
A marvelous everyday pen. This pen is my favorite. I have been ordering other
pens to try them out and I always end up coming back to this one. I have gone
through 11 of these pens so far and plan to continue using them. Some may find
the line too thin, but I like it. The rubber grip seems to wear out and get a
bit loose over longer periods of time (after replacing the inkwell once or
twice). The cap also becomes a touch loose over a similar time period. I always
put two or three of these on any Jetpens order I make. At the risk of making
these pens be out of stock more frequently, I would recommend this pen to anyone
looking for a hardworking, high quality, everyday pen.

The best everyday pen sold by JetPens. Can be used for writing and for drawing.
Waterproof. Mitsubishi (Uni Ball) makes fantastic products. My favorite brand.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Black
Awesome awesome awesome! I bought these because of the fine tip, and was
concerned about spending a lot of money on refills (reviews have said that the
ink runs out really fast). It does run out, but I have gotten through an entire
semester on two ink cartridges (and I take a LOT of notes). This is my go-to
pen.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.5 mm - Golden Yellow
Love the way this pen writes. Color is a lot like the Style Fit's golden yellow
color, with just a slight bit more orange. Very pretty light orange with yellow
color. Great for side notes or highlighting.

February 24, 2011
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Black
I thought that this 0.28 tip was a little bit scratchy. I ordered both the 0.28
and 0.38, and I have to say that I like the 0.38 better.
The ink flow is very consistent and the pen tip is just like a normal pen,
unlike the slicci which has a fairly sturdy tip and the hi tec c which has a
unconventional tip that looks nice and doesn't break unless you write extremely
hard.
I would say that this is a good pen for people who want to write small, and is
definitely better than the hi tec c 0.25 tip, which is tedious to write with.
Either way, I probably won't buy this again, due to the scratchiness, but it IS
a nice pen and is recommended for people who like very thin lines and dont mind
the slight scratchiness as much.

January 29, 2011
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Black
From the perspective of a university student, this pen is excellent. From
working out mechanisms in organic chemistry to just simply writing (notes or
essays), this pen does an outstanding job.
Compared to the Uni-ball Signo RT UM-138 (0.38), this pen is better built, has a
slightly more comfortable grip, has a much larger volume of ink, and writes with
the same "thinness" (but with a darker black). The RT's black ink always have
looked faded to me and they all definitely run out of ink way too rapidly or
even a mediocre writer/drawer/whatever.
The RT has the "clicker" ability (which I originally wanted this pen to be and
would buy another one if it were a "clicker") but the cap removal process isn't
a big deal. I've actually started to like the look of the cap and the way it
snaps on makes it feel like it's a high class pen.
Overall, this pen is one of the best that I've used.

This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - 6 Color Set
The colors are very fun and bright, but in my set of 6, the "baby pink" and
"pure pink" were very streaky, as if the ink was already drying up. That was
disappointing.

August 19, 2010
This review is from
Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Brown Black
Pen is as sturdy as the blurb says. Good choice if you like having a lot of pen
in your hand. Also comes in a few colors that Slicci doesn't, at least. This one
is my favorite, really solid color. Looks a bit like black coffee. I really like
coffee.
