I would not buy any of DJI products if I knew it was almost impossible to reach DJI Korea for repair. I own an Osmo Mobile, Mavic Pro, and Ronin M.
I've been happy with Osmo Mobile and Mavic Pro but Ronin M isnt satisfying at all. It isnt working properly and its been only a couple of weeks since I purchased it.
I use a Panasonic Lumix FZ2500 with Ronin M. It is the only camera I use. With it, Ronin M does not allow the upright mode. It seems weird. And while operating Ronin M, the tilting motor goes off randomly. My Ronin M is very new and lastest-firmware-upgraded. So behind all this annoyance, I tried to reach DJI Korea for repair. They never anwer(this is what I hate the most). I visited their website instead but I am not still allowed to book for repair. It doesnt even indicate any direction for Ronin. Is this DJI Korea's customer caring? I'm very upset and dissapointed.

Could you please let me know in which way you were trying to contact our tech support?
Did you sent email to support.kr@dji.com but get no answer?
