I just got this mod a few weeks ago and the top plug appears to be missing. This is just out of pure curiosity, but I was wondering if they are all like this or I just picked up one with it missing. It was like this when i got it from the store, and really didn't notice until I had gotten it home. I have tried to pull up images on Google but none of them show a clear picture of the button with it missing.
So far it has been working great.
