Good value sensor
Does the job well. Had to spend some time calibrating the potentiometer for my specific track surface, but once set, it's stable.

Reliable line tracker
Used this for a sumo robot edge detection as well. Very versatile module. Fast delivery too.

Decent but sensitive to light
Works okay indoors. Ambient light affects performance slightly if not shielded. Good for the price though.
