I to bought the S30R and after a couple of weeks the light stopped working. I contacted "GoingGear" and they quickly sent out a new light. (Great Customer Service!) well the new light is no better as it to is not working. I kind of gave up on it until seeing others are having the same problem. I have contacted "GoingGear" again and awaiting there response on how to proceed. It does make a good paper weight though.
