Excelent action camera for the price
Advantages: Light weight and filled with a lot of options. The shape of the camera is just gorgeous, It reminds me a little robot face. Very nice system to change the settings of every feature. Full control. Gyro mode. Leds to know different states, charging, recording, wifi, etc. Advice from the manufacturer of the fact that the so called 4K mode is interpolated. The price.
Limitations: Not the same shape of others, but only the underwater case, the rest of the accersories are common, so you can use them as you wish. Maybe battery life, it deppends on the use, but there is a new firmware that improves it.
