Advantages:
Very portable and easy to use (finger clip)
Real-time SpO and pulse data with visual display (bar, waveform)
Reasonable accuracy in normal perfusion conditions
Some models offer data output via USB / software / connectivity
Limitations & things to watch out for:
Accuracy may degrade under poor perfusion (cold fingers, low blood flow)
Motion artifacts can cause errors
The lower saturation range (<70 %) may have less accuracy
Battery life depends heavily on display brightness & usage
Ensure you get a variant with software/data connectivity if needed
Sensor calibration / drift over time periodic checks recommended
