Good sensor, slight wiring confusion
The module works well but the pinout wasn't clearly labeled on the back. Once figured out, it detects light changes instantly.

Potentiometer feels fragile
The sensor works but the adjustment knob feels like it might break if turned too hard. Functionality is okay though.

Great value for money
Bought five of these for a classroom set. All working perfectly out of the box.
