This is an electric gimbal for smartphones. It's a great product that can be used both vertically and horizontally. It corrects for camera shake and sudden movements by simultaneously moving the smartphone in the opposite direction with its motor, allowing you to take smooth, cinematic videos. It also has convenient features such as the ability to track a subject selected on the smartphone screen, and to keep the camera facing the same direction even when you move. However, it may feel slightly underpowered with larger smartphones. It can be operated in conjunction with dedicated apps for iPhone and Android. A dedicated case is included. A smartphone USB cable can be used for charging. Thank you.
