Other than our supplier’s default policy, once a return is agreed upon, you can ship your defective item to the provided return address that you should receive from us first. Please ship the order in original packaging with all the accessories and additional parts. If the Required Parts are not sent back, they will be billed for or expected to be shipped at a later stage. And only once all items have arrived will our staff check the returned product for testing. Include in your package a signed letter stating the reason for your return and the original receipt as well as any mentioned proof of defect, images, or a video, etc. It will help us to speed up the process on your behalf.

The purchaser (customer/buyer) is responsible for all shipping costs when returning an item. However, upon receiving the returned order, we will assess the product.

If you wish to return an unused product, please do so within seven days from the ship date for a refund on the purchase price, minus shipping, handling. Refunds will be credited to the original credit card used for payment in 24-48 HOURS after receiving the product back. We will charge 50% restocking fee.

Once your return is received and inspected, and if agreed for a refund, refunds will be credited to the original credit card used for payment in 24-48 hours. Please note that we will charge a 50% restocking fee once you return a product without any defect.
