This ring seems to provide good, accurate data. The only complaint I have is that it didn’t download my results two days in a row. I tried multiple times, but it didn’t work. On the third day, it started downloading fine again.
Been using it for one week. Fairly easy to set up and use. Battery life only 11 hours max. Just needed a cheap device for overnight blood oxygen to check to see if my CPAP was working properly. Will also loan it out to other people to check for sleep apnea. Downloading data initially wouldn't work but now it does have network connection. Still no overnight glucose readings. Hours of sleep and sleep Interruption readings seem accurate when compared to my CPAP . Easy to use the mobile app for understanding the data. The largest ring size fits snugly on my index finger so should have another larger size for morbidly obese people.
I was looking for a device to monitor my sleep without wearing a watch. This is easy to wear and gives many indicators for sleep. The data seems to be very accurate even for non-sleep data. I measured my blood glucose over three mornings and it matched the numbers given in my annual lab blood work. I've used it for a month and find it very valuable in helping me with sleep information.
It is nice to measure oxygen in blood while sleeping
