In general, I am satisfied with the purchase, in the application on the smartphone from the footage you can quickly mount something, conveniently. Transfer files over Wi-Fi at a frequency of 5GHz (if supported) to a smartphone. Stabilization works great, I rode a motorcycle on rural / field roads (and even just in the fields), the video is clear and smooth. Its pros: It shoots great, user-friendly interface, many video and photo shooting modes, accessories and mounts are easy to find, waterproof up to 10 meters without a case. Different cons: It discharges 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), on iOS the flight is normal right away.
