That means 70% of the drone buying public can expect to get shafted by the Chinese.... they don't have a business model like Europeans or Japanese do, to make something properly that will last. They want things to break or have a limited life so that you have to buy another one... a motorcycle that lasts 5 years then needs replacing because it has dissolved in the rain is better for business than one that lasts 40 years with hardly any spares requirements (my BMW)... that is there modus operandi. When it is working my DJI Air is very clever, the marriage of technologies, but the Chinese did not develop those technologies, they have spotted how they can be utilised though. I hope my Air does last because it fits my bag and provides pretty good image quality for a compact camera.
My next choice will be quality dependent, if DJI prove to be reliable for many years (already we are seeing IMU failures and the Air is only 3 years old - YES, ONLY) I don't consider 3 years to be old, my mobile phone that I use daily is at least 15 years old and still on the original battery and it makes phone calls far better than colleagues with their fancy yuppie phones that are forever struggling for signal. If the 1" sensor drone proves to be reliable, that will do for me, I shall then be judging on longevity of life and I believe Sony build high quality that lasts. If DJI match that, then I shall be happy to buy another one of theirs, but I have my doubts.
