Hi, welcome. I have a Mini2, and I really haven't had any issues with it. I do have a A2s and 2 P4Ps so it isn't my main go-to, but I do use it often for scouting, or just a relaxing flight around my own property. Since getting it, I think I have about 25 flights and maybe 6 hours in air on it, really not much, but I fly my larger birds for commercial work.
Some of the things I still have issues with are that it's obstacle avoidance is no where near the other drones, being I think mostly front, bottom, no side detection.
I do find that it is great as compared to lower end, non-dji models. It hovers well, and except for the occasional pilot error (I was doing some close quarters maneuvering to gain experience in my backyard and clipped a garden post breaking a prop), it has been a nice, reliable drone.
My point is, just like anything, there will be lemons. And their will be lots of great ones. Being a low end price point, the QA on it won't be as good, and with the numbers they can sell because of the price, you will have a lot more human error, or 1/2 stories about how the drone is in perfect shape, when it was in a tree the day before.
I have not had any charging issues using the fly more 3 battery charger, and the remote is the same as the A2S.
Hope it helps.
