For me - excellent DJI customer support
While other experiences here may vary, in my case, customer support - led by Avery and the team - were fantastic. Long story short - An Osmo Action camera I ordered arrived with a battery missing. I alerted the customer support team to this shortly after opening all packages. The team were absolutely brilliant and resolved the situation by issuing a coupon for a replacement battery. My general approach to customer support is how they respond when things go wrong. In this instance, they were magnificent. I already have a DJI drone that I am happy with, and I will continue to use DJI where I need good quality kit.
