Good value sensor
Solid build quality. Detection range is decent but depends on ambient light. Make sure to test indoors first.

Sensitivity varies
One module was a bit less sensitive than the others. Still usable after tweaking the pot. Shipping was fast.

Great for line following
Bought 5 of these for a school project. All worked perfectly. The output is clean and easy to read.
