Absolutely works well
The product works well, does vibrate which gives helps partially wakes my Dad which helps his O2 levels to improve. Setting the vibration to highest level and the threshold from 85% to 87% his O2 levels increased despite COVID. He is taking medicine now to fight the infection. I was told it is better to wake him than let him sleep with low O2 levels. This device seems to stimulate him enough that he seems to wake enough to breathe better. I think it is worth it. Only thing I swished it would do is notify me by the application. Know how t doesnât work that way but I am 99% satisfied. Better than I expected!

Totally inaccurate
I have been sick and bought this to monitor my O2. Instead of helping me, this caused me severe distress bc it was grossly inaccurate! I actually brought it with me to urgent care and wore theirs and this one at the same time and my 02 on this one was off by 7 points! and the heart rate on this one was way off too. This caused me an ENORMOUS amount of stress. It’s unfortunate because the fact that you can wear it at night and download it onto your phone with graphs and stats is really cool. This would be great, if only it were accurate. Without accuracy, it’s useless.

The alarm on the ring did not work
Having 02 problem l was interested in using the alarm when asleep.I called CS tech n did what he recommended.The alarm did not meet my needs so ring was returned.
Amazon Customer –
This device has helped to figure out some health problems I’ve had
Very easy to use, fairly comfortable to wear overnight, and seems to be very accurate. I had a previous one that wasn’t working right after about a year, so I was glad I had bought the extra warranty and they replaced it with no problems. This one has a thicker band of rubber/plastic around the finger so it’s not quite as comfortable as the first one, but I’m assuming the thinner ones may have been wearing out sooner so they made them more substantial. App is very easy to use and really gives you a lot of info about your sleep and breathing, including your pulse rate and how much you move during the night.
