Great value
Better than infrared modules I used before. The 8 channels give plenty of resolution.

Excellent for competitions
Works flawlessly on my sumo bot. The grayscale detection is much more stable than IR sensors in bright light.

Good sensitivity
Needs careful calibration for dark floors but once tuned it tracks lines perfectly.
