Hi!

I'd like to buy a Mavic Pro in DJI's Shanghai Store. I was wondering what happens if anything warranty related occures?

Will I have to send it back to a Service center in China to get it repaired or is there a worldwide warranty (like Apples)?

What if I buy DJI Care Refresh for the Mavic at the same time? Will the Mavic then be covered when I'm back home in Europe?

DJI warranty is not international, so yeah you will have to send it back to the country you bought it from.
I would suspect DJI Care Refresh is the same, but you can check the terms on the website.
Also you may have to pay import duty and tax when bringing it into your country for the first time.

I did hear that if the Mavic does need repair or service you have to send it back to where it came from when it was shipped to you --- for example my Mavic came to me shipped from California so I guess that's where I have to send it unless tolled otherwise  

Short answer,....just don't do it.

Long answer, you get zero support in Europe so read the short answer.
