Does what it said it would

This is a real oximeter like the doctor uses, and so easy to use and affordable!

It was so accurate and easy to use.I had purchased it in September of 2022. Today, it stopped giving a reading, so I put fresh AAA batteries in and it would flash as though it was going to provide a reading and it went black-no reading. We tried it several times.Update: we tried different batteries and it began to work fine again! Although the other batteries were new, apparently the device did not like that brand.

My unit is the exact one in the photo. It started right up once I put the batteries in. It took measurements that I would expect, so I am assuming it is accurate. (I have no way of knowing for sure if if it is accurate for SP02 until such time as I visit a doctor's office and match readings., so I'm not rating accuracy) The description of this being "not for medical use" is really a CYA statement. You can't use it as a constant monitor (although if you leave it on for a few minutes, readings will fluctuate as if it could be), but you can take snapshots of your SP02 and pulse at any moment. It's easy to read. My purpose is to take those snapshots a few times a day to ensure nothing dramatic is happening in my oxygen saturation, which happens to be an early red flag for COVID. Some people have seemed "fine" and then died within hours of visiting the hospital. Having a small, inexpensive and easy-to-use pulse ox device like this really fits the bill. As we're moving to more and more "telemedicine" visits, being able to report our vital signs to the doctor is essential!
