5 of 5 Outstanding customer service July 20, 2022
Reviewer: UrgentJedi from Newport Beach, CA United States  
I have just repurchased the latest version of the enormously popular American-made finger pulse oximeter from Nonin.  I am pleased to say that my Nonin 9590 pulse oximeter finally gave out - after 11 years of near daily use.  I purchased the unit from Concord Health Supply in 2011. Wear and tear simply took its toll. You will never be sorry to pay for an All American product. Customer service at Concord has always been second to none.

5 of 5 Great product July 15, 2022
Reviewer: Mildred from GA, United States  
This is the 2nd pulse ox I have purchased from Concord in the last few months. Hard to get readings on the "cheap" units and physicisn suggested this product for my husband. Works great and we take it with us to all appointments.  Had to purchase a replacement because I lost the original while on vacation.

Reviewer: Arlene Leonard from Medical Lake, WA United States  
This is my second one and they are super!  My first one after 16 years got flushed in the toilet 🤪 if you’re looking for a O2 meter this is the one to buy!

Reviewer: Mary Beth Small from Grayslake, IL United States  
The product seems fine but instructions were not provided - only a CD with the instructions.  I do not have a CD reader.  I requested instructions via a follow up email and did not receive them or a reply to my email.  A little disappointed.

5 of 5 Dependable/Accurate! March 15, 2022
Reviewer: MPowers from McKinney, TX United States  
I just spent 5 days in hospital with covid.  I have a drawer full of these things at home, with no consistency when it come to accuracy. My respiratory doc for my hospital stay carried the Nonin 9590 in the hospital using it on real patients!  If it is accurate enough for real world hospital use, it is accurate enough for me!  The cost is totally offset by the assurance that I am getting accurate 02 saturation levels!  Highly recommend!

5 of 5 Nonin Onyx 9590 Finger Adult/Pediatric pulse Oxime March 15, 2022
Reviewer: Carolyn Gillum from Fort Worth, TX United States  
I’ve had a hard time trying to find an oximeter that would be as accurate as my doctors. I purchased this and am very happy with it. I can be assured that the measurements I get now are pretty accurate. It has given me peace of mind.

5 of 5 Excellent Product March 10, 2022
Reviewer: Mildred Deal from Buena Vista, GA United States  
Needed a medical grade pulse oximeter. Ordered the Nonin 9590. It was received quickly.  We have been using it 3 days now and it reads quickly and values are consistent with those from the pulmonologist.
