In overall, I am happy with the purchase, as the application on the smartphone allows you to rapidly attach something in a simple manner using the footage. Files can be sent to a smartphone using Wi-Fi operating at a frequency of 5GHz (if this is supported). The stabilization works quite well; I tested it out by riding a motorcycle on rural and field roads, as well as just in the fields themselves, and the resulting footage is clear and smooth. It takes excellent pictures, has an intuitive user interface, a wide variety of shooting modes for both video and still images, is compatible with a wide variety of accessories and mounts, and is waterproof up to 10 meters without the need for a case. Many disadvantages: It drains quickly, sometimes freezes (not during recording), for example when turning off or viewing the gallery, at one fine moment it may not turn on and you will need a cable and at least a power bank (it happens just like that, sometimes the battery is discharged for some unknown reason), the application does not work correctly on Android (dancing with a tambourine helps), whereas on iOS the flight is normal right away. It is possible that the battery is discharged for some unknown reason.
