Good value
Accurate enough for indoor lighting automation. Pins could be labeled clearer on the board.

Okay for learning
Documentation was sparse, had to search online for code examples. Sensor works fine though.

Reliable sensor
Used it for a smart lamp project. I2C address is easy to configure if you need multiple units.
