I've been looking forward to this AI tracking gimbal stabilizer for a long time! For the first time using, I follow the posted instruction video and soon get the setup of this phone stabilizer, which is very convenient for me. PS: There are some stickers on the product for you to follow the gimbal setup steps. This is very careful. What impressed me the most is the AI sensor, which can quickly react to your gesture and launch an app or video for me. This face tracking mode can really free my hands from button controls. I believe it can work great when shooting HD videos. The tripod that comes with the stabilizer is very helpful for long video shooting. With LED backlight, sometimes it can work as a backlight. Overall this was a really good stabilizer for my phone and I recommend it to you!
