Easy to use
Simple to integrate if you have the right library. Would recommend buying pull-up resistors separately just in case.

Accurate readings
Compared this against a professional lux meter and the values were very close. Great value for the price.

Good but delicate
The sensor works well but the pins bent slightly during shipping. Easy to fix though. Accuracy is good.
