This is the reply I recevied from DJI today (sent for Gimbal overload):

The normal processing time is 10-15 working days, that is 3 weeks time.

Unfortunately we cannot speed up the delivery of spare parts, we are dependent on the delivery from China and also dependent on customs, when they will release the parts.

However, if we receive parts, they are 99% brand new parts/units, not refurbished ones. There is a good chance that your gimbal will be replaced with a completely new one. However we cannot promise in advance.

I'm left speachless at the last two sentences. Good chance? Seriously?

Hi travelrikk, we sincerely apologize for the delay. We will keep following up your case and get it solved as soon as possible.
As for your query, please refer to our policy.
"Please note that products and components presented for repair may be replaced by refurbished goods of the same type rather than being repaired. These refurbished goods have been tested and are similar to brand new goods in function and appearance. If any refurbished parts or units do not meet our quality assurance requirements, brand new parts or units will be issued. Any replaced parts may come with different serial numbers."
