First Guy: First drone was "perfect" until I backed into a bridge. Second drone has a camera issue which DJI tried to repair (sadly still faulty). Third drone was replaced and the Mavic at the bottom of the river. Seems okay. Don't see how that is a production problem.
I guess the point of the video was missed by you.
First Drone was the older original set when DJI was not under serious manufacturing pressure. It was perfect, just like mine and so many guys who got theirs in Nov, Dec. He crashed it, stuff happens.
Second Drone was made during the Rush period for DJI.
It had Jello in the video. Look up how many people have had this problem during that same period and you will be surprised.
Third drone was the replacement for the first. Its from the latest batch. Things have calmed down now at DJI and we have also seen less posts about the same issues like Jello or Black video, sudden ATTI mode etc. So yes he's right, the newest ones for the most part do not have the same consistent issues, they are less frequent and more random issues.
Second guy: Wait! I am taking off from a street! I need to make sure a car doesn't hit my Mavic! Flying in a "no-fly zone"? That's your problem.
Did you listen to the whole thing? It does not matter where he goes its telling him it's a NFZ! His friend is using a Mavic in the same location. The friends drone flies, his does not.
This another complaint we see on the forum from time to time, just maybe not as severe. This may be in part due to the really bad NFZ maps in China. In America they are also bad but in China it seems to be worst.
Third guy: This is something very dangerous! Losing GPS lock switches to ATTI mode. Incredibly dangerous! Maybe hit a baby. Read the manual maybe? The Mavic is a consumer product and some consumers are idiots.
Well yeah I think its dangerous if the drone just jumps out of GPS mode into Atti mode for no reason. This is another complaint that we saw a lot of on the forum during the peak sales of the Mavic. Once again the older models and the latest ones don't seem to have this issue very often.
