Honestly, once I got the hang of the controls, I'm totally blown away by this little gimmick. First and foremost, I ordered the mobile phone holder with motion tracking because I often video call my boyfriend and he regularly complains that I've disappeared from the picture again. I'm just a fidgety Phillipine.. The operating instructions didn't seem detailed enough to me when I first used them, but they actually contain everything you need to know for using the K&F Concept Tracking Tripod. Unlike one of my prescribers, the tracking tripod seems to respond better to movements of my left hand. At first I even thought it would only work with my left hand. But it works with both hands. The only important thing is that the built-in camera in the holder can capture the movement. So you shouldn't orientate yourself too much on your own video image and make the gestures too far up in the picture, otherwise the camera may not capture the movement. The movement tracking is independent of the use of the chat or video program and even works without recording a video or making a video call. Then it's just pretty pointless. When making video calls, the motion tracking reacts very sensitively, even the smallest movements cause the holder to move with it. Cheating your way out of the picture to secretly poo doesn't work :D Big brother watches all your moves. However, the camera cannot keep up with very fast or hectic movements. Even if you disappear from the camera area during your movements, for example when bending down, the holder remains in place - precisely because it no longer detects any movement. I have to be honest, I didn't think I would find the tracking camera so useful. Originally I really only wanted to use it for video calls. Now I can think of a thousand things I can do with it. It's also ideal for shooting videos where you're demonstrating something, without accidentally disappearing from the frame. For what the tracking camera can do, I don't think the price is too high. The only thing that could be better is the operating time, which is given as 2-4 hours depending on use. Here I would have wished for a stronger battery so that I didn't have to charge the device so often. Otherwise I have a clear buy recommendation.
