Reliable for projects
Used this for a final year project. Very stable output once the sensitivity is tuned correctly.

Needs calibration
Works well but requires some tweaking to get the right threshold for different surfaces.

Good value sensor
Solid build quality for the price. Detection range is short but accurate for close proximity tasks.
