This little ring is great. It’s easy to use And easy to read. I would recommend it for anyone with a breathing issue. It’s really helped me to know precisely when to use an inhaler instead of guessing. The fact it stores the information  means I have a well organized comprehensive record of information over a period  of time to show my doctor at MSK.
The alarm and sleep mode has given me real peace of mind and the device is inconspicuous and does not impair comfort so when you are ready to sleep you can. The breakdown of my sleep cycles is information of which I never would have been aware if not for the CIRCUL. Unlike other devices on the market this one is a hospital grade with precise data and alerts that can be life saving.  The ease of use, accurate information , and unencumbered comfort makes the CIRCUL ring well worth the price tag.

5 Stars!
Excellent tool to monitor O2 saturation and CPAP performance. Super easy to use with useful and simple data to confirm your CPAP is working properly each night. Highly recommend! Comfortable ring, and I don’t like rings or jewelry generally.


5 Stars!
Your ring is outstanding, I have thoroughly enjoyed wearing it, it has helped me understand my sleep patterns and O2 intake. Given the risk posed by COVID it is nice having a baseline. Their customer service is best in class

5 Stars!
I love my Circul. It determines the oxygen level in the blood during sleep. I am astonished how low O2 level drops. I do have sleep apnea and use a CPAP.
