Great for Beginners
Clear documentation helped me get started quickly. Sensitive to ambient light sometimes, but works great for intended STEM projects.

Reliable Line Tracking
Bought five for a sumo bot project. All sensors matched well in sensitivity. Great performance under indoor lighting conditions.

Easy to Integrate
Plug and play with my HelloSTEM board. No calibration headaches. The analog output gives fine control over line detection thresholds.

Good Value Sensor
Works well with Arduino. Wish the cable was a bit longer but otherwise solid. Calibration was straightforward using the potentiometer.
