As a result, the copter was delivered under warranty. The combination of characteristics for less than 10 thousand. It's tempting of course, but I'll probably look at other manufacturers. Syma has disappointed me so far.
Pros
Lightweight (registration-free), takes up little space and is easy to fold/unfold. Quickly calibrates before flight. The battery really allows you to fly more than 20 minutes - which is awesome. The picture from the camera is of average quality but with more or less normal color reproduction (I attach examples of shooting to the review). It immediately sends pictures to the phone in full size - if you break it or fly away, then at least the pictures will remain.
Cons
During test flights, problems arose - at some point the copter became uncontrollable and began to make pirouettes in the air with a roll to one side. The malfunction manifested itself several times and spontaneously - for example, it took off, gave the command to fly straight, and after 15 meters the copter rolled to the left side and, not responding to commands from the remote control, went around in an elliptical trajectory. Then, at some point, control was partially restored and it was possible to land it without damage. Maybe it just got caught, or maybe something is really wrong with the software (I met reviews that the copter flew off in an unknown direction).
I did not find the function of stabilizing the picture when shooting - everything trembles in flight.
Has pros:
The set is complete. Both the remote control and the quadcopter itself are charged from the mains.
Cons below:
Not very clear instructions, but you can figure it out.
