4 of 5 9590 pulse oximeter August 31, 2021
Reviewer: Mike from Longboat Key FL  
My only complaint about this product is the battery enclosure compartment. The closing/fastening mechanism has very poor latching causing the door to come off easily.
If it can be fixed or replaced, please advise.

5 of 5 Nonin Vantage Pulse Oximeter August 30, 2021
Reviewer: from , Broomfield, CO  
I purchased a Nonin Onyx Vantage 9590 Finger Adult/Pediatric Pulse Oximeter recently. I decided to go with a medical grade unit because I am totally done with the drawbacks of cheap oximeters. This unit does two things; it shows you your current oxygen saturation and your heartbeat rate. No other gimmicks I don't need. The unit takes just a few seconds to show your results. the cheapos take much longer to register, and the O2 content numbers vary greatly. In the long run the efficiency and accuracy of the 9590 is worth the price difference.

5 of 5 EXCELLENT PRODUCT June 16, 2021
Reviewer: from BATAVIA , IL.  
What a huge difference a made in the USA made oximeter makes compared to the cheap china drug store junk.  This unit was very accurate and fast in measuring life saving Oxygen.  It was more expensive but was cheaper than a trip to the hospital.  Thank You Concord supply!!

5 of 5 Purposeful design, fast and accurate April 23, 2021
Reviewer: Aaron Miller from Richmond, BC Canada  
Though it looks like something made in the 80s', it is a high quality measurement device, robust and very easy to use.
It's not just accurate but also very fast to deliver a reliable reading and quick to respond to small measurement changes.

5 of 5 Nonin 9590 Pulse Oximeter February 2, 2021
Reviewer: John P from Illinois  
Received the unit quickly and I am very pleased with the quality and performance of this Made in the USA product.  The higher price equates to a better value for me with the peace of mind of its accuracy versus questionable accuracy of lower priced units.
