Before returning goods, please contact us first to discuss the issues you are having. 90% of the time we are able to sort out the problem by giving technical support, without you having to send anything back.

If there are irremediable defects with the devices, you can return them back to us for repair or replacement under our twelve months warranty.

Please go to our HelpCenter to submit a ticket, and we will offer you a return code and our return address, along with additional important instructions.

Generally we advise you to return faulty goods by sending them through the Post Office rather than using couriers like DHL, UPS, and TNT. Normally it will take 2 weeks to return goods to us by Post Office.

If you did not buy your product directly from KAJOINHK.com, you will need to contact the vendor who sold it to you
