Mode syncing: Flowlight FS have a kinetic sensor inside - they know when they're spinning and when they're not! 


This means in some modes they can "sync up" by spinning them and then stopping quickly. It is most obvious in the rainbow modes (page 1, modes 1 and 2) since they constantly cycle through a range of colors. The lights may go out of sync and can be re-synced by spinning them all  fast and then stopping quickly. All of them will go into "static mode" at the same time - which will be the same color :)


All modes have kinetic awareness, and will know when your light is moving or still.
