Worth the money
I have tried cheaper oximeters without any luck. Nonin 9590 is the only finger oximeter that can give me accurate readings with my cold fingers.

Superb pulse oximeter
This item is expensive, but well worth the money if you need accuracy and precision in measurements of blood oxygen saturation and pulse rate. The device is compact and incredibly durable, and perfect for determining if anoxia is present - especially in remote areas such as high altitudes.

Nonin Onyx Vantage 9590 Finger Pulse Oximeter
This is the same pulse oximeter that the respiratory therapists used at the rehab hospital, and it's the only one that seems to be able to get a reading from me consistently. The PT and OT people used several different kinds/brands, but none of them would read me consistently. Even this one has some trouble sometimes, but it always works.

Best Pulse Oximeter
Nonin Products are accurate and very durable. I had the model 9500 for 23 years of good service. Im sure the 9590 will be as good or even better.
