Reliable light detection
Used this for a night light project. Very consistent triggering when ambient light drops.

Great for Arduino Projects
Works perfectly with my Uno board. Sensitivity is easy to adjust using the onboard potentiometer.

Potentiometer is tight
Functionality is fine but the adjustment screw is hard to turn without a small screwdriver.
