I have totally lost my faith in Dji products.  I had 2 mavic issues now i have a 3rd.  I initally had a "gimbal overload" couldnt resolve it via tech support or youtube sent the drone to DJI 3WEEKS later i received a NEW DRONE not a repaired one. So i thought awesome a BRAND NEW DRONE flew it had no issues for about 3weeks now i got a VISION SENSOR ERROR, went thru all the steps w Assistant 2, firmware update even reinstalled go4 app now i have to send it in AGAIN- ANOTHER 3 WEEKS! Mind you i haven't crashed the thing and have over 700k of flight rating.  So Im writing this to say KEEP YOUR MONEY!!!! My next step is to take them to small claims court since tech support said they wont reimburse me for my cost OR MY TIME FOR SENDIMG THIS CRAPPY PRODUCT IN!

Did this really require two threads?
