Help! Issues with DJI O3 Units - Need Advice

Broke four o3 units for the past half a year and DJI fixed them up for me for free. Don’t have any warranty, just plain account, air units bought less than a year ago from iha-race and drone-fpv-racer.

Types of issues:

Drown in a river - always red light,

Slammed into a metal pole - black screen camera,

Non working DJI controller controls after I bent one connector pin, bent it back, but still not working,

Did a crappy soldering on FC and got smoke from o3 after first battery plug in (Please use smoke stoppers).

The question is: I heard opinions that DJI vtx is pricy for freestyle, cause you will brake it and so on. But if they replace it so easily, than maybe it’s not that bad?
