What Our Customers Are Saying

"I'm a pilot and wanted to get an oximeter to replace my aging finger clip-style oximeter. A couple of features I really like are the vibrating alarm, which I set to high when flying to alert me before hypoxia sets in. And then also - no more batteries to replace. My old unit required a CR2 battery, but this unit lasts longer than I can fly in a day, and then some. I noted that it tracks my oxygen well as I climb to altitude in my unpressurized airplane and had a little fun experimenting with adjusting my oxygen bottle feed at 12,500' MSL from 90% to 98% blood O2 level. It appears to be very good quality and does exactly what I need it to. Compared to my old unit, my O2 readings are identical, so either they're both off or both accurate, but the readings seem reasonable and consistent and the heart rate sensor matches my Polaris HR belt, so that checks..."

"As part of my COVID-19 recovery, I need to monitor my O2 & PR as much as possible. O2Ring gave me that option plus some. The Reports were a big plus to my needs. As well as the alarm feature. I just wished it could be used in the shower and also use it while charging so I could gather a complete 24hrs stat of my system. I recommend this product for post-Covid patients still having O2 stability concerns and for Sleep Apnea patients to learn more about their illness."

"Post- COVID and in the recovery phase, I needed to keep an eye on Oxygen Saturation levels and Heart Rate. That's where the O2 ring comes in. It's very useful to know how these levels change with different tasks and the mobile and desktop apps provide a lot of information and trends. Customer Service has been responsive and helpful. I would highly recommend it."

"After spending 3 weeks in the hospital with Covid, after release and home on O2 ring has proven to be a great asset sleeping at night the downloaded graph in the morning provides me with a wealth of information. Now it will wake me when or if my oxygen level drops below a preset warning."

What Professionals Are Saying

Cajun Koi Academy

“Another reason why the alarm is so useful is that some people who sleep on their back or get into really deep snoring, especially if you have sleep apnea can drop their oxygen levels low, and so you can set the ring to vibrate and wake you up to remind you to re-adjust your position in your sleep. You can re-adjust and then slip right back into sleep and hopefully not wake up your partner as well.”

Dr. Adam J. Story, DC

“You can use this to show your doctor how you’re sleeping at night. That’s the real benefit of this. This could actually in theory save your life, because if you don’t know if you’re losing oxygen in the middle of the night, you may be totally unaware that you may have sleep apnea. And this type of product can alert you to consult your own physician and find out if you actually have a problem.”
