Official DJI Refund Policy: No Refunds, If Aircraft Has Ever Been Flown! Despite the clearly stated REFUND AND REPLACEMENT POLICY on DJI's website, which says that a "Refund" is available after Activation for any "Manufacturing Defect" within 7 days of receipt, the DJI Customer Service "Policy" from Corporate, according to Derrick, the manager I spoke to today at Customer Service, is that: "NO refund will be issued, if the aircraft has ever been flown, no matter what. An exchange is the only option." Surely a battery that delivers only 15 minute flight times when rated at 28 minutes is a manufacturing defect, and a controller that loses all signal at 1.3 miles under optimal conditions instead of 3 miles is also manufacturing defect, as is a gimbal that squeals like a stuck pig, when handling the aircraft with the battery on. However, that isn't even up for discussion, as discovery of these manufacturing defects requires flying the aircraft, and flying the aircraft voids your REFUND opportunity, so you cannot discover any manufacturing defects that affect range and battery life and performance, which would entitle you to a refund under the written DJI Refund and Replacement Policy. Can you say CATCH-22? DO NOT BUY DIRECTLY FROM DJI ONLINE! Your only recourse is an exchange for another unit with the same manufacturing defects! If you ALREADY have bought a P4 from DJI, and are within 7 days, and may want to return your P4 for a refund, don't fly the aircraft! Return it to DJI for a refund while you still can, and purchase from Apple instead. The sales tax at Apple will be cheap insurance! When you buy from Apple, they offer a 14 day no questions asked satisfaction return, even if flown, without requiring any manufacturer's defect!
