Review on 📱 Versatile STARTRC Mavic Air 2S Tablet Stand: Securely Mounts 4-12 Inch Smart Phones and iPads for DJI Mini 2/Mavic Air 2/DJI Air 2S/Mini SE/Mavic Mini Remote Controller Accessories by Allison White

The tablet fits perfectly in soft spring-loaded sliders. The whole block is plastic, a bit light and flexible for the heavy large tablet I use, but it works well. The band is barely long enough and won't stretch anymore. I have a few questions. What the heck is that 3D printed little clip for? Looks like part of a prototype. And what is the additional (small) quick-release fastener on the belt hook for? (see photo) Not a big deal but it would be nice to know what each of these items is for.
