Cool Factor awsome
Looks Awesome
Body feels awsome; its ribbed aluminum, well made
writes average, the Zebra Espina performs better

Ink is is a nice darkness, but feels drier has a slight drag. In comparison, the Pilot Bps GP has about twice the gliding feel.

This pen is good for heavy handed writers, I have a lighter touch and I only use it to sketch so I take it out when I want to impress people.

Worth the money? If you love good looking well designed pens and dont write or sketch extensively, this is a fun pen to have in your collection.

I bought the "cheaper" powertank series first about six months ago. It was my daily use pen and I absolutely loved it. It never seemed to have any ink-clumping and always wrote on the first time. I decided to get this High Grade series because the only issue I had with the cheaper version was after a prolonged daily use the end where you screw in the clicker started to crack. It was a problem if I ever clicked/unclicked the pen multiple times quickly. The pen would explode apart.

Now with this high grade series I can already tell that this won't be an issue after prolonged usage. The barrel is aluminum, seems durable, color is vibrant. It is a lot thinner than it's "cheaper" counterpart. The pictures definitely don't do it any justice. I was impressed by its beauty upon unwrapping the package it came in.

I purchased the Uni-Ball Power Tank Smart Series High Grade hoping that it would function well with Field Notes' new Expedition series notebooks. The synthetic paper doesn't treat most inks well and I hoped that the Power Tank would hold up well.

I pleasantly surprised when it arrived. The Power Tank functions exceptionally well with the Expedition notebook's synthetic paper. It even outperforms Fisher's Space Pen cartridges; worth noting are line quality (the Power Tank lays a very smooth line whereas the Fisher refills tend to skip) and dry-time / smudging / smearing (the Power Tank's line dries far quicker, drying to reasonable levels in nearly a quarter the time of Fisher's offering in my not-so-scientific study).

With traditional paper the Power Tank performs admirably, as well. I have no complaints with its writing performance.

The barrel's knurling (for lack of a better term) is very nice. It provides an excellent grip while not being too aggressive. Also, it's rather nice looking; certainly a plus.

Overall, an excellent pen. My only wish? A version with a red barrel. Although, black, brown, and blue seem nice, too.

I LOVE THIS PEN.! The barrel looks very professional and is made of aluminum. I love the way it writes.! It is smooth and doesn't require to much pressure to write. The ink flows well there is no clumping. I don't know what to say about this pen.!(: It isn't very heavy either.

I love this pen! For everyday use, it's great. Very smooth writing, nice dark ink, and a nice slim size. I haven't tested out all the more "extreme" uses yet, but I'm very satisfied so far.

Not good for sketching/drawing.
Although it is a nice looking pen with a smooth glide to it, it leaves a lot to be desired when drawing. I sketch in pen directly, mostly ballpoint, and was looking forward to using this one based on reviews.
However, when laying down long smooth lines or even quickly sketching this pen has the unfortunate habit of blobbing randomly. It makes for a very choppy look and is overall just so frustrating. Unfortunately I also bought a refill and now have something I won't ever use. I love the ease of use of a good ballpoint pen vs the fountains and more complicated set ups. I was hoping for a slick upgrade for a ballpoint but am left still looking.
