Fast shipping and great performance
Arrived quickly and was well-packaged. Installation was straightforward for my husband, and our mahjong machine runs like new again. Very satisfied with this purchase.

Excellent sensitivity
The imported sensor board is a significant upgrade from the generic ones I tried before. No more false readings or jammed tiles. Worth every penny.

Works but required extra adapters
The unit functions well, but the connector pins didn't match my specific table model exactly. I had to buy separate adapters to make it fit. Product description should mention compatibility specifics more clearly.

Good quality but instructions could be clearer
The sensors work great and seem very durable. However, the wiring diagram was a bit confusing for someone not experienced with electronics. Once figured out, it works perfectly.

Perfect replacement for my old table
My mahjong table stopped recognizing tiles after years of use. This kit was exactly what I needed. The installation took about an hour, and now the shuffling is smooth and error-free.

Saved my game night!
We were about to buy a new table until we found these parts. The optical probe is extremely sensitive and picks up every tile correctly. Highly recommend for DIY repairs.
Q: Is there a video tutorial available for installation?
A: Yes, we have a general installation guide video on our product page that covers the basic steps for replacing the optical control unit and sensor board.
Q: What should I do if the sensor still doesn't detect tiles after installation?
A: First, ensure all connections are secure and the polarity is correct. If issues persist, try cleaning the optical lens with a soft cloth, as dust can interfere with detection.
Q: Can this handle dirty or slightly worn tiles?
A: The high-precision infrared sensor is designed to detect tiles even with minor wear or dust, but heavily obscured or damaged tiles may still cause reading errors.
Q: Will this fit a table manufactured in 2015?
A: It depends on the specific brand and model. Most tables from that era using optical sensors are compatible, but please check your current sensor voltage and connector type before purchasing.
Q: Do I need special tools to install this?
A: You will typically need a small Phillips head screwdriver, wire strippers, and possibly a soldering iron depending on your table's current wiring setup.
