Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
You yourself know the sticker position to be unusual.
But if it were a resealed bag, you would notice stressing on the bag, wrinkling or fine creasing, where or near where the sticker was removed before.
Perhaps there are merely (if you see no such signs of prior removal) two different schools of sticker placement: the Horizontalians, and the Verticalians, as it were.
But after assessing that aspect of this problem, go on to test everything about the xpro2. Run it through some very thorough tests of all its functions. Leave nothing out. Also examine it carefully for any sign of prior use, dropping or banging (chipping, or dented corners, or unexplained odd-colored marks anywhere on its case, are all good signs of this), etc.
If it works fine you have a good product.
Does this answer your question?
If so, let me know so that I may close this case.
If not, let me know what else you need to be advised about, please. Thanks.
