Terms of Service

General
This site/store is operated by us. By purchasing here, you agree to these Terms along with our Privacy, Return, and Shipping Policies.

Products & DIY Nature

  • We mainly sell DIY project parts/kits/spares.

  • We are responsible for the material/workmanship quality of parts; however, due to differences in tools, skills, environments, and third-party components, we cannot guarantee everyone will achieve the same finished results as in our demos/videos.

  • Some items require customer-supplied or 3D-printed parts (enclosures, brackets, etc.) to complete the build; such requirements are stated on product pages—please confirm your conditions before ordering.

  • We provide drawings, firmware/code, and build references for free for learning and personal use; no guarantee they fit all setups or ensure assembly success/performance targets.

Orders & Payment
Placing an order confirms product details, compatibility, and any self-supplied requirements. Pre-payment only (e.g., PayPal/credit card). We may cancel/refund orders that fail risk checks (e.g., suspicious orders/addresses).

Shipping & Delivery
Shipping is governed by the Shipping Policy. If items arrive damaged/short/wrong, contact us within 48 hours with photos/video.

Returns & Support
Returns/refunds follow the Return Policy: for change-of-mind returns, the customer pays return shipping and the refund deducts the actual outbound shipping cost (even if shown as “Free Shipping”).

Safety & Compliance
DIY projects may involve electrical/mechanical/thermal risks. You assume responsibility for assembly/use, comply with local laws/safety standards, and take protective measures as needed.

IP & License
Unless stated otherwise:

  • Site content (texts/images/videos) is owned by us or our licensors;

  • Our files (drawings/code/docs) are licensed for personal, non-commercial use only; no resale/redistribution or branding use without permission.

Limitation of Liability
To the extent permitted by law, products and materials are provided “as is.” We are not liable for indirect/incidental/consequential losses arising from improper assembly, third-party parts, environment, or modifications.

Governing Law & Disputes
These Terms are governed by the laws of the People’s Republic of China (without conflict rules). Disputes shall be resolved amicably first, then by competent courts in China.
