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.

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.

i bought this pen expecting to be able to ink drawings for watercolor since it said it was waterproof, but this pen smears SO easily i'm incredibly disappointed.

also, as others have said, the ink flows out of the pen very smoothly, but the actual design of the pen makes it a bit uncomfortable to write with. it may just be that it's a bit wider than im used to

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.

Great pen, although this one seems to be a little scratchy? The pen doesn't quite flow across the paper like my other pens do. I bought this pen first in Bordeaux Red and it was so great to write with that I bought a bunch of other colors. I'm hoping it's just this one being faulty, so I'll probably buy another one later.

I bought the 0.28 and it didn't even work because the tip was too thin; this one is much inkier!

I am a fan of fine point pens. the sharper the line the better. I am the type that would dry out a gel pen so the ink drew a finer line towards the end of the shelf life. the UM151 is great. I have not written with a 0.38mm pen until 7 years prior and I haven't looked back. the sharp point feels amazing on all sorts of paper and smoothly glides along without too much tearing during the writing process. the point is almost always smooth -- writing is a breeze and so much fun. a great everyday carry pen, precise and smooth.

A bit better than the .28 - consistent line with little pressure.
