Good chance you won't have problems, but also a fair chance it's a refurb. However the refurbs are supposed to be systems returned during their return policy. However in my experience with them for my P3 and
M2Z, the supposedly repaired gimbal on my P3 looked new, and the RC for my M2 which was supposed to be repaired for a broken antenna also looked new.
However if there's any deviation or discrepancies, it's hard to fight them. Their HQ is in China after all, with seemingly limited business presence in the US.
I didn't realize they had a repair center in TX. They had me send my M2 to CA back in October.
