Customers like the performance of the blood oxygen monitor. For example, they mention it works awesome, the bluetooth-enabled app is excellent, and it works just fine on a TOE.

Customers are mixed about the accuracy of the blood oxygen monitor.

Also Works on My TOE... For Hands Free Monitoring over time
This little Bluetooth device (plus the ViHealth APP from iTunes or Google Play)tracks Oxygen Saturation and Pulse Rate over time. Its readings pretty well match what I see at Doc Office, and it's AMAZING it can do it for under $20, when similar devices go for more than $150!!!Out of necessity and invention, I discovered today that it works just fine on a TOE, too!I was talking to my doc on a call and she was saying SPO2 needs to ideally be in the mid-90's or higher, and I reminded her mine is historically quite a bit lower... down in upper 80s to low-to-mid 90s tops.She asked what it looks like while I'm sleeping and of course who knows? I don't check it like that.But I supposed I could, if I used my Bluetooth monitor and wore a GLOVE or something to keep it on.Then I thought. let's verify what is RIGHT NOW over time. But having to hold the device on my FINGER while I sit here and try to type... I can't get much done. I kind of need my HANDS!But I said to myself, "Self, I said, you have a few other monitoring appendages available not doing much while you type. Wonder if this thang will work on the TOES!?"And sure enough... same reading; same numbers, fits fine...Great! So now I can get a much longer-time-scope reading SPo2 from my FOOT while I keep working.Perfect!

5.0 out of 5 stars Like the idea to connect with your phone
Reviewed in the United States on January 3, 2021
So I tried this as soon as I got it. Gotta admit I was hyped with the Bluetooth function.

First off, it came with a lantern, battery, instructions on how to use, instructions on how to connect with the phone and the app you need, the certificate that looks like when it was last checked and the warranty and who to contact for trouble shooting papers (they’re all tiny papers)

It uses two AAA batteries and like all lanyards they’re a pain to insert. It wasn’t too bad, I’m just bad at it.

Just the basics that it has the pulse, the oxygen saturation and a wave form and a couple of indicators that I don’t really look at like each heart beat and how your heart is pumping. Plus the battery indicator.

So the cool thing I like about this is the app and that it shows you your data from your phone. I had an easy time connecting after I downloaded the app it asked to connect to the pulse ox and it connected without any issues. I own an iPhone X if you need to know.

I tried it on myself and my 4 and 6 year old nephews. It gave me a reading within seconds but I did notice that it had trouble reading the 4 year old’s finger since he had tiny fingers. After using his thumb, his reading came through. The app did store all the data which I thought was cool.

I wanted this for possible monitoring in case I need one at home but I just like these to be on hand especially if a vital signs machine isn’t readily available and a patient is having issues.

I like this idea so if a patient does need to record at home, this can give you something to refer to

Overall, I like it’s first impression, will update if there is any issues or if there are any nifty things I found after using this for a while
