Warranty & service

This product includes 180 days of warranty service, starting from first power-on after setup and use.

After an app membership period expires, the device continues operating independently, though some app functions may be limited. Official firmware updates will continue to improve supported functions; more app features will be released in future versions.

Selected replacement accessories are available. Contact support if an accessory is damaged. Do not flash or use unofficial firmware, as this may affect device stability and after-sales service.

Risk notice

Solo mining results are probabilistic. A successful block depends on network difficulty, device hashrate, operating time and chance. Block results shown on the page demonstrate the query function only; they do not guarantee a BTC reward after purchase.
