The Kingii is an emergency life preserver that you can strap right to your wrist that inflates in seconds and brings you straight to the surface of the water.

WOAH NO WAIT WHAT I AM A LIFEGUARD DO YOU KNOW HOW MANY MORE LIVES THIS SHIT CAN POTENTIALLY SAVE???!!!
As someone who likes doing water-related things like fishing but intensely fears drowning, I’m gonna need like three hundred of these, okay.
If I had had one of these I might have stopped having so many anxiety attacks and actually finished my damn swim lessons after the teacher tried to drown me that one time.
