INTERNATIONAL SHIPPING
Your package may be subject to the customs fees and import duties of the country to which you have your order shipped. The recipient is responsible for all duties and taxes incurred. We cannot determine these fees during the checkout process.
In most cases it takes 5-14 days to be delivered to your address. As we ship via DHL/UPS/FedEx/YunExpress, the product gets handed to your local post office on arrival in your country/district and as such, delivery times will vary by country depending on the efficiency and expediency of your postal service.
Please don’t refuse the package because of the customs or taxes charges when the item is delivered. The carrier won’t be able to return the items to us unless these fees are paid. Our only option is to abandon the package in customs and if this happens, we won’t be able to offer a refund.
Notes:If the wrong address is provided by the customer, and this leads to the package being lost or otherwise becoming unrecoverable, the customer shall bear the loss. We will not replace the order or issue a refund.

AFTER-WARRANTY POLICY
Questyle products are designed to be long-lasting. They are made of durable materials that are robustly tested in our Reliability Testing Lab. The longer you use your device, the better for the planet and environment. If your device from Questyle is out of warranty yet needs repair, we offer our customers a paid repair service.
