Great upgrade for older tables
I was worried my older automatic table might be vulnerable to manipulation. This detector verified the program integrity instantly. The anti-operation upgrade feature is a nice bonus.

Compact and reliable
Love how portable this is. Fits easily in my bag when I travel to friends' houses for mahjong. The battery lasts through our entire weekend tournament without needing a recharge.

Essential for serious game nights
We use this at our local club to ensure fair play. The sequence recognizer is incredibly fast and accurate. It gives everyone peace of mind knowing the table hasn't been tampered with.

No more suspicions!
We had some doubts about luck during our last few games, so we bought this. After running the verification, we found out the table was fine, but just having the detector there stops anyone from trying anything funny.

Works well but needs practice
The device works as advertised, detecting irregularities in the shuffling program. However, the interface took me a little while to get used to. Once I learned the buttons, it was smooth sailing.

Good concept, pricey
It does what it says and detects cheating artifacts effectively. My only hesitation is the price point; it feels a bit steep for a casual home player, though probably worth it for clubs.
Q: How long does it take to scan a full set of tiles?
A: The sequence recognizer typically completes a full verification cycle in under 30 seconds, depending on the table's shuffling speed.
Q: Is there a warranty included?
A: Yes, every Sijing Mahjong Machine Detector comes with a standard 1-year manufacturer warranty covering defects in materials and workmanship.
Q: Does it require an internet connection to function?
A: No, the core detection features work offline. Internet connectivity is only required if you wish to download firmware updates or sync logs to the cloud.
Q: Can the device detect magnetic cheating tools?
A: Absolutely. Our program verification and sequence recognition algorithms are specifically tuned to identify anomalies caused by magnetic interference or external manipulation devices.
Q: Does this work with all brands of automatic mahjong tables?
A: Yes, the Sijing Detector is designed with universal compatibility for most standard automatic mahjong tables available on the market.
