Duplicate Serial Numbers

Same serial number R/L.

Perhaps a printing error?

Could have happened with a breakdown/restart or when adding new paper stock.

Sloppy regardless of the reason. What else in their QA process is failing? 

If they're "pretty high end" and they told you they can't keep their serial numbers sequential without duplication, I'd have a hard time believing they'd support or warranty their products if something happened. Major red flag for the brand. 

red flag.
