Overall, it has the same quality as my Bamboo Tornado. It is strange looking, yes, but it is quite unique and surprisingly comfortable to write with. The leather is not crocodile leather, don't worry, and its texture is almost like having grip. The pen has the knurled knob at the top that is just so easy and fun to twist. The clip is also flexible so it's very easy to attach it to things (and you don't have to worry about the cap popping off). This particular model is a liquid ink rollerball but the refills I have for it will fit.
The ink is of course very smooth, no skipping whatsoever, and only bleeds through thin paper or where I have saturated the page with ink (like when I try to doodle). This is not uncommon with liquid inks though.
What I was really impressed with was how fast the ink dried! It was dry almost insantly. Good news for the lefties of the world.

I don't think I'd have gone out and bought this particular model of pen myself (mostly because I prefer shinier things), but the pen itself writes with the same great quality you'd expect of a Retro 51. If you are looking for a crocodile-looking pen, this is a great choice, and it's certainly unique!
