I shipped my MA2 from NY to DJI in California on August 19 for two bad motors. 15 days from the time I shipped it out I received my package from DJI. When I opened it I was expecting to find my MA2 with two new motors. To my surprise they ended up sending me a new MA2 rather than replacing the two motors. I'm impressed with how fast the whole process was completed especially when you consider it was traveling for 11 of the 15 days.
