Good value

Decent sensor for the price. You need to add some code filtering to get a stable reading.

Works as described

Sensitive to movement but that is expected for this type of optical sensor. Happy with the purchase.

Solid analog output

I connected this to an oscilloscope and the waveform looks correct for a PPG signal.
