This is a fine pulse oximeter that meets F.D.A. standards. I needed it after a COPD exacerbation, and it is working very well. Concord and its Customer Service were very helpful when the postoffice, partly because of a bad snow storm, didn't manage the delivery on time or to the right address. (USPS usually does a good job, but this was a mess.)

Nonin Onyx Vantage 9590 Finger Adult/Pediatric Pul

This is my second NONIN oximeter (lost the first one). I can't say enough great things about the product. It is my determination that the cheaper name models are not worth the savings. Buy a good one at the beginning as your life may depend on it.

Works reliably and repeatably so far

This device gives repeatable results so far. It always works so far. User reviews informed me that less expensive/robust devices may give erratic/untrustworthy readings because of design/construction weaknesses/insufficiencies and algorithmic/calibration insufficiencies. Wrong and erratic readings from a complex device of this type are useless. Delivery to my house was excellent.
