Great for beginner bots
Worked perfectly with my Arduino project. Calibration was easy using the potentiometer.

Good value
Sensors are responsive. One LED was slightly dim but functionality is 100%.

Does the job
Sensitive to ambient light so shield it properly. Otherwise works as described.

Reliable tracking
Used this for a competition robot. It handled sharp turns well due to the 4 channels.
