I'm not sure how long I've had this little light. I bought quite a few and have given them out to my daughters and friends. I had a friend the other day tell me hers wasn't working. I made several inquiries but ended up asking for the light back so I could have a look.
My initial observations are that nothing appears out of the ordinary. No loose pieces or parts, no squashed interior parts ( these lights can suffer from being over tightening ), battery used is fully charged, emitter looks to me intact, thread are clean, so
.
It may be something more complicated but for the price I'm not bummed.
