I have in the past 7 or 8 threads back have talked endlessly over this ridiculous CF suject that I rest my case on it now!.This is the proof of the pudding and if they were "inferior" props - tyres then WHY does DJI supply them in the box that you buy the drone in?Look at the pic and code,send it to DJI and ask them why do they put such crappy props in the box so that you now can damage your new "toy" as somone so indignantly put it.Cio.
Does your 'barcode' even look remotely like a DJI barcode?
