Excellent Precision
Used this for a smart lighting project and the color temperature readings are very stable. Integration with ESP32 was straightforward.

Good value
Works well for the price. Documentation could be more detailed regarding the register maps, but community examples helped.

Pinout unclear
Had to trace the pins on the PCB to confirm SDA and SCL locations. Once connected, it functions correctly.
