This a charging cradle/puck for the Kids Smartwatch model LT21. I needed a simple easy to use charge station for these watches, but most I found were design as stands or displays, but I needed something more compact and secure if charging on the go or in my car. This is designed to fit snug in place. To assemble you just feed the charger port through the side hole and slot it into place. Firmly press down so it is snug and flush. After just slot the watch into the cradle and it will begin charging. Hole at the middle of the cradle is designed for easy removal of the watch. Just push the watch out with our finger and it will easily pop out.
