By mookiemorjax

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.

By dbajraktarevic

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.

  From the perspective..., January 29, 2011

By jus...

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.

By bri...

This is my absolute favorite pen. I picked up a bunch without much consideration when I lived in Japan a few years ago. After a few months, I realized just how amazing they were. It was the first time I had ever said to myself, "wow, what a great pen." Then after moving back to the states I realized they were impossible to find outside of Japan. Not even art supply stores had them. I finally found them on Jetpens-what a godsend!

They're the best!

By ashleyspurlin

I will admit, I have been a Pilot fangirl for a very long time. It wasn't until I became bored with my typical Pilots that I decided to venture out. And boy am I glad I did! I will admit without reserve that I am very quickly becoming a complete fan of the Signo line. I've never been a big fan of needle points and was slightly disappointed that the smallest non-needle point offered by Pilot was a 0.38. After branching out to other manufacturers, though, I'm finding plenty of alternatives. Now if only I could make a UM-151 fit my Pilot Cavalier...

  This is my first one..., December 29, 2011

By jordanr1186

This is my first one of a few pens purchased from Jetpens.com. I heard of this site on a podcast. I am a long time Pilot G-2 fanatic because it's what is sold here in retailers(USA). The Pilot G-2 was the best I knew, but they normally always carry the 0.7mm which is a bit too large. After reading many reviews, I decided to try the Uni-ball Signo DX UM-151 in black in sizes 0.28, 0.38, and 0.5mm. I am very pleased. They write very smoothly compared to my Pilot G-2 0.5mm pens. Also, if the fact that the ink does not bleed with water, it makes them that much better. Of course people will probably argue that taking off a cap is too time consuming but, to be honest, I think it keeps the tip from drying out much better than retraction. I also purchased a few other Uni-ball products and I am hooked on Uni-ball. I work in the manufacturing sector, and everything I see from Uni-ball is high quality, at very reasonable prices. Thanks jetpens, now I'm hooked and will never buy from office depot or staples again. :)

By tiffanykiok

Excellent pen...I was originally unsure of whether to buy this pen or the 0.28mm version. I am glad I chose the 0.38mm thickness because it's very thin (but not too thin) and doesn't skip. It writes clearly with sharp precision, and the pen itself feels comfortable to write with. Black pigmentation is good and doesn't appear faded.

The ink refill stopped working halfway through for 2 of these pens that I bought, but it was great while it lasted. I hope my 3rd one doesn't die.

By hippocheese14

First things first:
The pen writes incredibly smoothly and the tip is a lot more durable when compared against other lines such as the popular Pilot Hi-Tec-C.
The rubber grip makes extended writing a little more bearable, but it is not all that effective, and I feel that the grip is placed a little too high for my writing style.

Now the problem:
No matter how orders of this pen I make, the pen begins to skip after merely a few days of usage. I try my hardest to avoid getting anything stuck within the tip of the pen to cause any skipping, but the problem seems to be inevitable and it's quite a nuisance. It's a huge problem, so it detracts one point from my review.

By bugscottiebug

This pen is amazing. Compared to some other .38s that barely write, this pen is incredibly smooth and amazingly sharp.
