【Delivery Time】

1. Express Shipping (DHL, UPS, FedEx, EMS):3-10 working days is a good rule of thumb. These services prioritize speed and often offer features like next-day or guaranteed dezlivery by a certain date (for an additional fee).

2. Air Mail (China Post, Hong Kong Post):7-35 working days, depending on the destination country. This is a more budget-friendly option, but it takes longer because it has lower priority for shipment.

【Important Notes】

Please follow the product’s instruction manual carefully for installation and debugging to avoid damage to the product.
