A:The USB Charger is generally responsible for the problem. If the charger light does not light up  when connected to the toy, contact us or your local retailer for a replacement charger. 
The magnetic charging contacts on some toys can be very sensitive, make sure the charging toy has complete and steady contact for the duration of the charge.
Note: The toy will not operate while being charged. Make sure your toy is disconnected from the charger before attempting to turn it on.
If issues persist, contact KISS TOY at sales@kisstoy.com for assistance.
