DJI has really wonderful Authorized Retail Store. I bought Air Unit, but this unit was defected so I returned it and claimed my warranty. First they told me it would be ready in 5 days, but it didn't. After two weeks, I contacted them again, but they did not respond. Last week I called them again and they told me that this week it will be done. After 30 day they were not able to solve my problem - a simple piece-by-piece exchange (the problem was that my Air Unit was not able to link with goggles). So now i will have to wait until they return my money and buy a new one. I spent 30 day waiting for nothing. Great support!  I thought the Authorized Retail Store has direct contact with the DJI, but I found out, it all being handled by another company.

Hi pRo_lama, we are sorry to hear about the difficulties that you encountered. May we know the detail information of the authorized retail store that you referred to? We'd like to forward it to the related team to investigate.

Today, I finished my claim warranty and they gave me new Air Unit.

The name of the store is - TELINK, spol. s r.o. (https://www.djitelink.cz)
