You need to pay return shipping fee for returns. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days). You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. NOTE - the 140-day starter is from the day you have the tracking info, NOT from the day when you place the order. If you don't receive the parcel after 140 days, please feel free to contact us for a solution (refund or reshipment). UPDATE - Since the COVID-19, the longest shipping time we encounter is over 140 days with free shipping. Thank you for your understanding and support. After confirmation, we will send you a replacement product for free. If there is any defect or defect in the product you received, please contact us in time and attach video or picture description. If we confirm that the goods cannot arrive or are lost, we will refund to you. Also, the plastic makes it more lightweight and portable. We will contact the express company for you. Something to note - Topre actuates from the top, as opposed to the middle like other switches. During COVID-19, If you do not receive the goods after 90 days, please contact us in time.
