I love UM-151. Just one thing I really don't understand, though. These guys are $2.5 each, and if my math is correct, if I buy 8 it should be $20. Now this set is actually $1 more expensive!! Shouldn't it be the same price, if not cheaper?

I bought this set for my husband to use for highly detailed maps that he draws. He needed a very fine line but with vibrant color. The pens are perfect for what he's working on, and I'd recommend them to anyone looking for a fine line gel pen. We're both interested to see how long the pens last, we've had problems with some other brands of gel pens rapidly running out of ink.

I've had a limited edition pink Uni-ball Signo UM pen with me (exactly the same like this pen, but has a polka-dot design) and it survived for a LOOONG time. These pens are my favorite, as they have an excellent quality.

PROS
- Smooth and easy writing
- Comfortable grip
- Even though it's stated as a 'gel pen' it doesn't smear, smudge, and dries quickly
- Waterproof
- Ink color is vivid and matches the pen color (I hate it when colors are lighter than how they looked like!)
- Doesn't bleed
- Long pen lifespan. No, really :p

CONS
- Expensive; for me, but it's WORTH IT.

Gave these to my daughter who is an artist and she was very pleased. She particularly likes their fine point which is difficult to find.

I've been a big fan of the Hi-Tec C (0.4mm) pens ever since I laid my hands on them. Compared to the Hi-Tec C pens, however, the Uni-ball (DX) UM-151 (0.38mm) is much thinner compared to the Hi-Tec C. I personally love how smooth these pens can write without any scratch noise. In addition, IT'S WATERPROOF! The Hi-Tec C pens are not waterproof (one drop of water can mess up the ink on paper).

I gave a Hi Tec C pen for my boyfriend last year and he broke the tip of it. I bought these pens this year for him and he said he absolutely loved it (better than the Hi-Tec C).

I use these to draw what I see with the microscope (histology). These colors are good for most of the stains I use, but replace the pink with "pure pink" to get a better set.

This ink does not run, even if I spill alcohol or water on a drawing - which happens a lot more often than it should.

I highly recommend these for laboratory use.

Darn, I was just about to order these, and they're sold out. Please restock! ^_^ I LOVE the couple of DX UM-151s that I have - now I need them in more colors!
