Gilbert Ives - I agree with your point, as the seller is not specifically saying it is a prototype. They are are saying it may be a prototype and up to the buyer to decide, nothing wrong with that.
For what its worth, I have purchased an item or two from this seller before and it was
100 percent legitimate. With a feedback rating of 100 percent and almost 1000 transactions to their name, the seller must be doing something right.
