We ship items worldwide using fast express services with tracking numbers via DHL, FedEx, or UPS. The estimated delivery time is approximately 4 – 8+ business days.

3. Buyer's Shipping Account

We can ship using the buyer’s own courier account. However, the buyer must arrange the pickup and provide us with the printable shipping label. Simply providing an account number is not sufficient. If you use a FedEx account, please also provide a control number or reference number.

4. Order Processing Time

Orders are processed within 1 – 3 working days after payment is received. If any item is out of stock, we will inform you of the revised delivery time.

5. Shipping Address Accuracy

We only ship to the confirmed address provided in your order. Please ensure your delivery address is correct when paying via PayPal or credit card. If the address does not match, we reserve the right to cancel the order and issue a refund. Payments via bank transfer (T/T) or Western Union are exempt from this restriction.

6. Transit Time

Shipping transit time is provided by the carrier and excludes weekends and public holidays. Delivery times may vary, especially during peak or holiday seasons.

7. Customs Duties & Taxes

The buyer is responsible for any customs duties, taxes, or import charges. If you require a declared value adjustment on the shipping invoice, please inform us in advance. Otherwise, we will declare the actual paid amount.

(For small shipments to the continental United States, our prices include import duties, and buyers from there will not be required to pay any additional import-related fees. Import duties and related charges for bulk shipments are subject to final confirmation.)

Please note that in most EU countries, declaring a lower value is not permitted, and the actual transaction value must be used. For EU countries, Switzerland, Norway, and Ireland, an EORI number or VAT number is required for customs clearance.

8. Customs Clearance Assistance

If required, the buyer must provide reasonable assistance to the shipping carrier for customs clearance in their country.

9. Inspection Upon Delivery

Please inspect the goods in front of the DHL/FedEx/UPS courier upon delivery. If any damage is found, request official damage documentation (Proof of Damage) from the carrier and immediately notify us by email with photos of the packaging and products.

10. Warranty Policy

The LED display parts listed at our online shop are covered by a 12-month quality warranty. For some hardly obtained legacy parts, we may provide used items that are covered by a 6-month warranty. The condition is indicated as "used" for those items on their product page.

If products fail under normal use within the warranty period, we will repair or replace them free of charge at our side. Damage caused by improper installation, power surges/electrical overload, water ingress, or unauthorized modification is excluded.

The buyer is responsible for all shipping costs and any applicable import duties or taxes for both returning the items to us and receiving the repaired or replacement items.
