Long story short, sent I1 in for repair or replace camera and requested my pieces be returned. Received I1 but no pieces as promised. Contacted DJI they said "We dont return pieces" I explained to them that I want my pieces back or if they are keeping they need to issue me a credit toward my repair. They then apologized and told me my pieces had been discarded and they were sorry but they would send me some replacement pieces. They sent everything but my camera which is what I wanted, anyway have no use for so here ya go. Thanks for looking.
