Am very pleased with my purchase of the Nonin Pulse Oximeter..I was in the hospital when it arrived so had it brought to hospital to compare with pulse ox monitor there..The Nonin 9590 registered the same as hospital monitor app.90% of the time..the other times is was only 1# +/- on ox and pulse..

Accurate when compared to my doctor's machine. Can't live without it. Free case is okay. A lot easier to do battery changes.

Portable Finger Pulse Oxymeter

I am recovering from moderate emphysema. The instrument allows me to monitor pulse and O2 sat during vigorous exercise. Early results are encouraging, supporting the hypothesis that, conventional wisdom notwithstanding, people with COPD can recover considerable lung function through disciplined hard work, with a concomitant improvement in overall health.

Onyx Advantage 9590/Excellent Quality

The Nonin 9590 Onyx Advantage Finger Oximeter is an excellent example of American made quality. I had a Chinese Finger Oximeter which was slow to settle on a reading and was inaccurate, especially for the SP O2. It also didn't update for several pulse beats and would jump between high and low readings before finally giving a stable reading. Another problem was that it was overly sensitive to any motion. The Nonin 9590 on the other hand is stable, able to produce an accurate reading in seconds and is much less sensitive to motion. A superb product from America.
