14 days return policy
You can return an unopened and unused product within 14 days of receipt of the item. You will have to pay return shipping cost for sending the item back to China (or to Oregan, USA and UK for smaller items).
You can return an opened and tested product if it doesn't work as expected in your setup, or doesn't fix the issue (in case of the USB isolator).
Contact us by replying to the sales confirmation email to arrange this.
