My Mav3 Pro flew into a river. I used Flyaway to order a replacement. They sent the replacement with a DJI baseball cap, then DJI called to tell me they were sending an email with a coupon for a battery. I figured $10 off but..it was for a FREE battery. The coupon only worked for Canadian customers (where my replacement Mav3 Pro was shipped from). I emailed thanking DJI and telling them it didn't work for me, a US customer. They sent another link for US customers and my free Mav 3 Pro batter just arrive. Shipped from New Jersey. Go figure.
