Returns Policy

You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

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. 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).

If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.

Shipping

We can ship to most countries worldwide, but please note that some remote countries will incur additional shipping charges, which are estimated based on distance.

Since the product is relatively large, we provide two transportation mode options. The first one includes freight mode, and the transportation time is about 25 days. The second charging mode is about 3-7 days. Please choose the appropriate charging mode according to your needs.

Our products do not include on-site installation service. However, every item comes with a detailed installation manual and access to step-by-step video tutorials to guide you through the process with ease. For the specific installation guide and video link for your product, please contact our customer service team. We are committed to ensuring you have all the resources needed for a smooth and successful setup.
