This device does not come with instructions. It is not intuitive that a battery is needed in the plug itself because the plug is watertight. It took a while to figure out the device needed a battery and how to open it. In the process, of installing a battery I broke the on/off switch. Unfortunately, it does not seem to be repairable. So it is going to the trash can without ever being tried out. I will retain the controller and perhaps will find a compatible toy for it someday.
I didn't get the product neither the refund
