How long will it take for the Harbison UAV to return to the factory for repair and send it back?

It will take 15 days at the earliest.

The factory should establish a feedback mechanism so that customers can check the maintenance progress online. Or three days of active SMS notification. And set the maintenance time limit.

/kloc-If it cannot be repaired within 0/5 days, the new machine shall be compensated. Regard the customer as God.
