Howdy again,
Thank you all for your replies.
The backstory on these is I purchased them off of Ebay. I know, I know, I should never buy gars off of Ebay. But the guy had sold other PAMs, and the feedback from those buyers was positive.
Anyway, I get this box and it's not sealed. I tell him I want exchange for a sealed box, and he will only give me a refund.
After hearing from my BOTL, I think I will take him up on the refund.
Thanks all,
jcwbnimble.
