I've seen other, less expensive devices throw things. I chose this device because I really liked the hanging construction, it is well thought out in my opinion. I later realized that they also do a double drop version, I could get that version for more drop options. They contain information to put you in touch with installation and operation videos, but the device actually turns on and off in seconds and breaks it down into small parts. which can easily be stowed in my Mavic2 case. The device itself works as advertised, either rotate the model two turns counter-clockwise or attach the included Nav LED sensor, program the Go4 app to toggle the navigation LEDs using TX C1 or button C2. The entire unit is 3D printed and the finish is pretty decent, thoughtful again.
