I'm a pilot and wanted to get an oximeter to replace my aging finger clip style oximeter. A couple features I really like are the vibrating alarm, which I set to high when flying to alert me to 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 I need it too. 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.

I have used it for sleeping out of curiosity as well and it was comfortable on my ring finger through the night. it was a tight fit on my index finger (I have an XL sized hand), although I noted that it provides the same read out on my thumb, index and ring fingers.

Very interesting results after 1 week of use. Night 1 pic on left shows problems that worried me. So I took some corrective action in the first 6 days (better meal at dinner, not eating after 7pm, nose spray, better hydrated, changed pillows, etc), took advantage of the ring feature to buzz me when my SPO2 dropped low, monitored every night, and last night's results are on the right. It's a noticeable improvement, and more importantly, I feel much better. I'm data-driven generally, so this device is great for me.

The computer program needs to have a header that can be used by labratories to put their info , company name and phone and address.
it also lakes the ability to type in different patients info. know it only allows on patient ..

If you wont this product to be used in clinics and labs you must make these changes.
I have tried to reach out via e mail but have not had any resposes.
I would buy 10 for my lab if these simple issues where corrected

Just received the O2Ring and wore it for the first time last night. Was very pleased and impressed with the cellphone app report (attached). It captured in expandable detail my O2 level throughout the night and the vibration alarm woke me several times at the low O2 level I set. Just recently learned of my sleep apnea, which I've probably had for over 30 years and I'm hoping to use the O2Ring to help determine the affect of various therapeutics I plan to try on at home. I've started using the CPAP but I don't like it and am hoping to find an alternative solution. Good-luck with your efforts.

I was looking to monitor my O2 saturation throughout the day as I had failed two ‘6-minute walk tests’. I found the ring cannot monitor during the slightest movement making it useless for my purposes.

Overall quite useful. Here is my wish list of improvements.
1. Needs linux version of software or ability to output data in say .csv format for archiving/studying data.
2. Ring could be more comfortable to wear all night. Perhaps a wrist band version might be more comfortable?
3. The is a missed opportunity to have a morning wake up alarm, given the device already has a clock and vibration capability.
4. A minor thing but going to bed after 12am, then the following night going to bed before 12am shows up as the same night.
5. More space in the text box for notes especially because of point 1.
6. An even dimmer display setting.
7. A dimmer red light if possible.
8. A progress bar or percent charged indicator for charging.
All this sounds a lot but I really liked the device and it shows great potential. Once my studies with it are complete I probably won't wear it again but I definitely do not regret buying.

Having tested positive for covid 19 this ring has given me peace of mind .
I monitor my oxygen levels throughout the day as this is very important for knowing when a hospital visit is needed.

Sometimes works correctly but sometimes I have to wait or turn it off and reuse it again to go back to normal operation.
The charging cable doesn't work, I thought the device has issue but after I used another cable the problem resolved.
In overall, a device with this price has to be more reliable and efficient.
I think it's so so.

Very useful device. I appreciate the vibrating alarm that you can set to alert you to a chosen level of oxygen saturation.

As a doctor myself I am keen to use this on patients who might have as sleep apnea.

I can see what is going on as I sleep. I can print out copy for doctors, and for me it helped me not take a higher milligram of meds, because my heart rate was too low in my sleep. Thank GOD I had this.
