I never thought that I would like this tattoo pen as much as I did. It took me by surprise, and I am guessing that you'll also be a bit shocked.
I generally don't care for the grip shape that you find on this tattoo pen, but on this one... it just works. It feels right in your hands, and if you're someone who understands the need to have a fatter grip (less finger & hand fatigue after long hours of tattooing) you'll love that this grip lends itself to that. It's already quite fat.
The fit and finish on this pen is beautiful, and I only wish that the cube-like battery (very unique, by the way) would come in a coordinated color. I'm okay with it the way it is, since it's really just a matter of aesthetics.
The pen runs very nicely with a bit of noise in the higher ranges (beyond the working range), and a little bit of vibration. Not bad, at all. The battery supplies 7-8 hours of reliable power, and yet is very light. It has little effect on the balance of the pen. The battery has a good working range, 4.0v-12.0v, and you can jump around in 0.5v increments, or (if you're like me) dial in using 1/10th of a volt increments... very fine.
The stroke is a nice 4.0mm, and there are positive click stops when you turn the barrel.
The pen is really sporting an unique shape, and I think it's beautifully machined, as well.
Readout on the battery is digital LED, in multi color. It's bold, bright, and easy to read. Gives you plenty of info, and faces you as you work. You can see what your settings are at a quick glance.
Comes with some extra electrical parts, a clip cord, charging cord, and in a wonderful, quality carrying/storage case. Case has a zipper closure.
I'm really smitten by this pen. While it's not the best running pen among it's price range, it's certainly one of the nicest, and runs well enough. This is a good choice for both beginners and advanced users, alike.
Nicely done, Xnet!
