I have only had this for one week. So far, the best one I have owned. Better than the ones bought at local drugstores.

Evaluation of this unit
February 28, 2023
Reviewer:
Charles Sherwood from Salt Lake City , UT United States
I am a retire physician and have purchased at different times four of these pulse oximeters: personal use, church emergency kit, and friend with asthma. I have used them for emergency evaluations in each situation and am very pleased. Two counter intuitive caveats that should be understood about putting in the batteries: 1) the battery lid must be pushed toward the small gap at the finger opening of the unit to open (don't pull toward you) (2) The batteries go in reverse directions to make the unit operate, however, the two springs side by side make you think the negative ends of both batteries fit against the springs. The unit won't work if the batteries an not put in exactly as directed. I don't store batteries in the unit in case they spoil and ruin the unit. In an emergency situation, these non-intuitive steps and cause confusion and delay.

Great for O2 sat spot checks

Reviewer:

Good device for home or office use for spot checks. LEDs give an indication of pulse signal strength and therefore accuracy of readings. Older patients and other patients with poor perfusion may need their hands warmed prior to use.

Nonim 9590

Reviewer:
Les from Alba, TX United States
This Nonin 9590 is a replacement for another Nonim that we have had for 10 years. My experience with Concord has been a great experience with no issues and shipping was quick and easy. We love the 9590 and it is a great product.
