Just a heads up to anyone experiencing this issue. The current recommendation from Pioneer support is to order control vinyl direct from Pioneer. They are not covered under any type of warranty, so buyer beware of shop return policies before purchasing.
The warped vinyl will be bowl/cup shape warped which renders the control vinyl unusable for scratching.
I have confirmed that amazon will refund warped records. The DJ Hookup will not. Currently in the process of possibly receiving a refund from Pitbull Audio.
Found the below posts as well about this same issue, so I'm assuming it was a bad press run (as some I've seen in other places and here are also included with mixers, not just purchased on their own).
