Long story short, I received a MS clone today and the box did not have the O rings. Rather than dealing with customer service in Hong Kong, are there any sources Stateside? I also have an Ace Hardware just down the road- if I knew what sizes these are supposed to be (no manual of any kind included in the package), I'd go ask them if they had any in stock.

Oh, yeah, plugged battery into light, hit the switch, and nothing happened. I'm hoping the battery was just fully drained and that I don't have a faulty battery or light.
