Catdaddy,
So did you get it resolved yet? I would trace back to the dealer first, and then the manafacturer, since the dealer was technically the last person to handle it, other than the mailmen.
I wouldn't jump to any conclusion about the dealer either. One small boo boo shouldn't constitute to poor service. I wish we could be a little bit more tolerent with some things. But that's a whole different topic.
Anyway, i hope you get your Arc AAA soon. I'm sure it was just a mix up, either during shipping (which is out of your and the dealer's control) or the manafacturer. I highly doubt that the Arc AAA left the factory like that, but you never know. And if it did, i really don't understand how NOBODY spotted it in the shipping process. It sure is puzzling. The amount of turns it requires to remove the head of an Arc AAA rules out accidental removal.
My bets are on the postal office. I bet some postal worker wanted to check the insides of the Arc AAA just to make sure that there wasn't any dangerous substances inside of it...and then forgot to put the head back on. If somebody wanted the light, they would have taken the whole thing, so i don't think it was theft.
