Shipping
Domestic (U.S.) Orders:
For domestic orders, we offer three options. The most economical is Ground Shipping, fulfilled by either USPS or UPS Ground. With Ground Shipping, your order will be shipped the day after it’s placed. Typical delivery time is 2~5 business days after shipment. If your delivery address cannot be served by USPS, please include a note with your order to specify your preferred carrier.
For expedite service, we offer UPS 2nd Day Air, as well as UPS Overnight:
• UPS 2nd Day Air: NO service guarantee. If delivery is late, the shipping cost is non-refundable.
• UPS Overnight: Includes money-back guarantee. If delivery is late, we will refund the shipping cost.
For UPS 2nd Day Air or Overnight, to qualify for same-day shipping, your order must be placed by 3:00 PM Eastern Time. Orders placed after this cutoff will ship the next business day.
NOTE: the UPS service we use neither accepts nor delivers packages on Saturdays. So orders placed after 3:00 PM Friday will be shipped the following Monday. Similarly, orders placed after 3:00 PM Thursday will ship on Friday but arrive the following week. Please understand that while we strive to ship as promptly as possible, once your package is shipped, we have no control over its delivery time, especially in the event of weather-related delays or other unforeseen circumstances.
International Orders:
For International orders, we offer two shipping options:
• First-Class Mail Package: Fulfilled by USPS. It’s the most affordable option, but NOT trackable or insured. If you choose this option, we are NOT responsible for lost package (it’s rare but does happen!) Delivery time varies significantly by country, often taking 4~6 weeks, and in rare cases, 8~16 weeks, especially if held up at customs.
• Express Shipping: Fulfilled by Fedex or UPS. This option is trackable, insured, and typically delivers within 4~8 business days.
NOTE: Buyers are responsible for all VAT and customs duties, which vary by country. This applies especially to orders with Express Shipping (Fedex or UPS), and to European destinations.
Despite the additional duty tax payment, we strongly recommend Express shipping for its speed, tracking, and reliability. If you choose First-Class Shipping: please be aware that we cannot be held responsible for lost packages or delays due to customs processing.

We are NOT responsible for damage or malfunction resulting from improper usage, including (but not limited to):
