I am satisfied with the purchase, I recommend Hero 7 for purchase, but it is better to take a closer look at Hero 8. The touch screen is very convenient to use. Some pros: 1. Shooting quality. 2. The camera can be used without an additional box (tested on two trips in sea water). 3. Touch screen. 4. Additional screen in front of the camera. 5. It is possible to view the footage on the screen on the back of the camera (without connecting to a computer, etc.) Different cons: 1. Series 7 is used in a set with an additional mount-box (in series 8 this problem was solved by placing flip-down mounts at the bottom of the camera). 2. Gaps between the lens and the body of the camera (poor assembly in series 7. In series 8, a molded body was made in this place). 3. Price. 4. Expensive accessories.
