I bought this Moza MIni-S because first of all the price is great, I love that it doesn't take up so much space and a bring a tripod. This is my second Moza product, compared to Mini-mi, it is more user-friendly. It comes with a small battery, but it needs to be charged before use in order to work properly. It is important to read the instructions before use, download the Moza Geni app (available for IOS or Android). Always check if you update the firmware so you don't have any problems with it and calibrate the gimbal every time you switch phones as they all weigh differently. Some app features: object tracking, timeless, video recording, slow motion. Another thing I love about this gimbal is that you can have the app you like the most to take pictures and it comes with a camera control cable so you can stick with your favorite app. I have a Galaxy S9+ and I'm not complaining about using it with this gimbal.
