Great aquabox! Smartphone control. Its pros: Rich equipment! There are all kinds of fasteners. The quality of the video is on the four, the tone of the picture tends to fill up in blue. Ability to charge and shoot at the same time. Operation from an external battery when fully discharged. With its cons. It gets very hot, a weak battery, the buttons sometimes work twice, and in general the buttons cause a feeling that they will not last long, sometimes they stick. It writes sound very poorly, besides the sound is mono. 60fps mode is cheating - double frames are recorded.
