I work in a laboratory that analyzes municipal water samples. I use this pen to write on wet sample bottles with no problem whatsoever. Recently we had a massive leak in the roof at the lab and many binders of handwritten data were soaked with water. It was interesting to see the ink of other pens running down the paper while the ink from the Power Tank was still intact and perfectly legible.

Such a great pen! the ink is very smooth, doesn't skip or blob. The feel of the pen in your hand is fantastic, it has a kind of grippy, controlled feel to it. The pen itself is a bit bulky, but that is really a benefit for me, having large hands. The retracting mechanism is probably the best out of all the pens i have, the spring mechanism has a very firm, efficient feel to it, and i have had absolutely no problems with it. When buying this pen, remember to load up on refills, you will not regret it! Trust me!

This pen writes non stop anywhere. My favorite pen. I've had a dozen now and am now ordering refills too as the pen body lasts for more than one complete refill.

I have used the Uni Power Tank pens for years and prefer them to all other pens. As someone who for many years judged working dog trials, I had to have a pen that would write in damp weather, write when at an odd angle and not flat on a table and was good under all conditions. Those are the Uni Power Tank pens, in my estimation.

The refill in this pen (I have two which I found somewhere several YEARS ago) is the nicest, never skip, never blob writing thing I've ever used! The body is comfortable with a very nice grip.

The reason I only give it a 3 out of 5 is the clip. On both of mine the clips did not last a month. One has been held in place by an o-ring since then, the other missing most of the clip.

Both are down to about 1/2" of ink left.

I plan to try the Smart series to see if it has a better clip. AND to see if it writes as good as my old ones!

i didn't care for the ink in this pen. it's a light color. the pen does have a good feel to it, but it didn't make up for that ink for me. it gives me a feeling of the pen not working proper.
