A friend and colleague has had some pretty major reliability issues with his DJI kit over the past couple of years, and I know for certain he's the kind of person who looks after his stuff and isn't a heavy user. His drone pretty much fell out of the sky (after returning to DJI, was "repaired" and returned), the controller screen has since failed, and his gimbal thumb-stick stopped working.
He's said he won't buy DJI again.
So, here's the issue - I'm sure your friend is right, drones don't have the kind of reliability we've gotten used to in other consumer electronic products.
By their nature, consumer drones go in harm's way, and have little to no redundancy for anything to go even a little bit wrong. They're also very lightly built, since low weight is critical. I
had a trip to Hawaii a couple years ago where I crashed my Mavic Pro through my own stupidity, and had my Mavic Air stop flying because of a manufacturing defect in the cooling fan common to the first production batch. I ended up going from two drones to zero in an afternoon, and had to buy a Mavic Pro from Best Buy to continue flying and shooting. DJI fixed my crashed Mavic for about $150 for a replacement gimbal and replacing a broken propeller arm, and they replaced the Mavic Air under warranty, both within a couple weeks.
Was I cranky as hell that my backup drone wouldn't fly one inch once I arrived in Hawaii? Yes. Was I bummed that my primary drone broke from what was a fairly modest crash? Also yes.
But this is just life with aircraft that sell for well under $2K new.
The miracle is that these incredibly capable aircraft exist at all at the price points they do. DJI's Mini 2 runs under $500, and even the prosumer Mavic 3 is under $1500, with the very very good Air 2S in the middle, under $1K.
The reality is that DJI's stuff outperforms almost everything else on the market on most metrics. There are some other options that win on one specific category, and might be better if that particular feature is a core item for your needs.
Realistically, right now there's only limited alternatives to DJI from the bottom of their product line up to about the $3K mark. Once you get above that, there starts to be a lot more pro-level or custom-build options.
