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.
