dji secret. A combination of flight distance and flight time registered by your dji app compatible drones. Someone asked it on the official dji forum, but I forgot. I´m actually amazed, that those Sparks still fly... I loved it. Had same design...
Funny you should mention dw_store13 & the Neo 2 Fly More Combo (Drone only)+3 batteries+charging stand. I ordered this combo from them on Friday, Nov. 14, and received on Monday, Nov. 24th. Only addition fees were shipping & CA sales tax.
OEM...
