What is the warranty?
Warranty terms are set per order and stated on the invoice. Spare units and parts are usually a better arrangement for volume buyers than a return programme.

Support & after-sales
What happens after the container arrives matters more than the quote. Here is how we handle it.
Common questions
Can firmware be updated after shipment?
Yes, where the build includes our OTA channel. We can push updates to units already in the field, or hand you the image to distribute yourself.
How are defects handled?
Report with the serial, the failure mode and a photo or video. We diagnose against the production batch and come back with a root cause, not just a replacement.
Do you supply spare parts?
Remotes, power adapters and boards can be shipped alongside the order so your local service partner can handle repairs without shipping units back to China.
What about certification queries at customs?
We supply the certificate pack and test reports for the revision you bought, which is what customs normally asks for.
Can I get a sample first?
Yes. Samples ship before any production commitment, and we would rather you test it properly than trust a spec sheet.
