Love it. This is the first such stabilization device I've used, although I often shoot video on the go (e.g. skiing and sports) using both cell phones and GoPro cameras. The stabilization effect combined with the target tracking feature is awesome, it gives you so much freedom to shoot from different angles while moving back and forth with your targets. The children were very happy about it! Definitely recommend. The only thing I was missing, and I thought could easily be fixed, was more direct and clear instruction. Surely they can do better. Before that, users should know that in order to interact with the flash drive, you need to install and use the ZY Cami app, and then you can use all the controls and features on the flash drive to start video recording on your phone as well and stop as camera zoom, etc. All in all, a great thing if you want to capture quality video of moving subjects, especially if you're moving too.
