I didnt think to take any WIP shots, but I'm going to tear it apart later to paint the buttons, so i will take some pics, and write up a short worklog.
The paint on my mx500 was starting to wear out, and i didnt want to paint it. :p
It is slightly padded, and the texture gives it great grip, I am probably going to paint the side buttons black also.
I tried my first one yesterday, I found it at a small local store close to my friends house. I actually got a noticeable caffine buzz from it, but that was also right after drinking a 20 oz. tripple shot mocha. I thought it tasted pretty good too though.
