Caddx FPV 4K Action Camera

Performance:Loose part inside Unbox last Friday, can config in the caddxfpv app via wifi but notice loose part sound inside. While the recording seems working fine for now, my concern is the reliability of the product plus the loose part will for sure add vibration to the IMU sensor, which is not good for those who wants to use gyroflow data. I'm requesting warranty claim but unfortunately there is no aftersales network in Malaysia and I'm asked by Caddx to ship it to China/Hongkong, which I have to bear the shipping fees. I think Caddx will fail to capture market if they don't improve aftersales network at Malaysia, and user also being let down by their quality/reliablity issue. The image quality wise is good, video stabilization yet to fully reviewed, so to be fair, hence the 2 stars.
