Shipping
Domestic Orders:
For domestic orders within the U.S., we offer two options. The most economical is Ground Shipping, fulfilled by either USPS or UPS Ground. With Ground, your order will be shipped the day after it’s placed. Typical delivery time is 2~5 business days (including Saturday). If your delivery address is not served by USPS, please leave a Custom Order Note with your order to specify your preferred carrier.
For expedite service, we offer USPS Priority Mail. Typical delivery time is 2~3 business days (including Saturday).
NOTE: We are based in Massachusetts. For customers in the New England area (MA, CT, NH, VT, ME, RI, and east parts of NY and PA), UPS Ground will typically deliver in just 1 business day. Choosing an expedited service will not be cost-effective. Instead, when placing your order, you can leave a note requesting UPS Ground with same-day shipping—this option provides the best value.
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 2~4 weeks, and in rare cases, 8~16 weeks, especially if held up at customs.
• Express Shipping: Fulfilled by UPS or DHL. 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.
Liability
We are NOT responsible for damage or malfunction resulting from improper usage, including (but not limited to):
• Using an incompatible or out-of-spec power adapter / transformer
• Power surges or incorrect wiring
• Exposure to unprotected environment
• Damage from lightning, floods, or other natural events
• Software bugs, programming errors, or using third-party software
Support Policy
Support is available via our support website, email, and forums. We do NOT offer phone or live chat support.
Please consult our support website first, which includes tutorial videos and articles covering user manuals, common questions, and troubleshooting steps.

For mission-critical applications, we recommend maintaining a backup controller to minimize downtime in case of hardware failure.
