I literally just got my MP back today and I was extremely impressed with the DJI care + experience. I made a warranty claim (with the extended warranty from care +) and provided them with enough proof that my gimbal was broken... And they sent me a Shipping label and I sent it in. At first they told me there was "no fault found" but then I provided my evidence again and they fixed the gimbal but sent me a (I think brand new but probably refurbished, definitely a different aircraft) MP back. They did give me my old battery back though...
To conclude. I didn't pay a cent. I had my MP for 2 years previously and I'm effectively getting a whole new lifetime.
