Can someone tell me what the normal warranty period is when purchased from Amazon?

Hi there, you are recommended to purchase DJI products from DJI authorized channels, you may refer to this website: https://www.dji.com/where-to-buy. For the warranty period, please check the "Warranty Period of Main Parts" from our official website: https://www.dji.com/service/policy?site=brandsite&from=nav. Hope this helps. Should there any other concerns, please feel free to let me know.
