5 of 5 Excellence throughout August 29, 2018
Reviewer: Robin Nelson from Sandy, OR United States  
The Onyx 9590 is fast and trustworthy.  Worth the money.  My $15 OTC unit was inconsistent and slow.  Pay for quality.

Customer service was very, very good.  They promptly worked out a bug not of their creation and were patient in the face of my IMpatience.

5 of 5 Great product, fast delivery June 11, 2018
Reviewer: Roberta Butterfield from Minden, NV United States  
Used this as a school nurse and hope to put it to the test on the hill with ski patrol, currently using on family members.  It is a fast, accurate read.

As a repeat customer I am never disappointed.  The nonin pulse ox is high quality and reliable.  Deliver time meets or exceeds expectations.

5 of 5 Quick shipper and superior oximeter February 6, 2018
Reviewer: Joy from Hacienda Heights, CA United States  
I'm a respiratory therapist and heavily rely on the Nonin Onyx for its accuracy. There are many different models on the market but none compares.

5 of 5 Professional and Dependable November 17, 2017
Reviewer: LB from Rosemead, CA United States  
This is my 2nd purchase from this store. They are thorough with their descriptions of their products. They do not cheat you on their pricing. The product always arrives safely with all the mentioned accessories and in the appropriate amount of time. The Nonin pulse ox is very reliable and I wouldn't purchase any other. I am replacing the same Nonin pulse ox I lost. I have tried other brands in the hospital. Nonin is my go to-quick check for SpO2 and PR.
