    The ring holds promise, but its large size causes it to catch on things. That along with the yearly cost for complete information caused me to return the ring.

    I already have an Apple watch SE and wanted to compare it to Oura. I wore my Oura for the past 5 months and my numbers were consistent. Two weeks ago, I went on medication that Zi will need to take for several years. There's no way to update my info. to inform Oura that my HRV will be elevated compared to what had been tracked so far. My sleeping heart rate was between 42 and 46 every night. After I started my medication, my sleeping heart rate went up to 56 to 62. This isn't bad, but it's much higher than what the ring was tracking. So basically, my ring now thinks there is something wrong with me and tells me to Pay Attention every day. I stopped wearing my ring for over 10 days and then put it on again, and now there's something terribly wrong. Lol! I'm sticking with my Apple watch! I was expecting more intelligence with Oura.

    Red light leaves behind almost like an irritating heat rash on the finger when worn for extended periods of time like you are supposed to. They also charge a monthly fee to even use it to its full capabilities. You would think paying for a $4-500 ring would be enough to solve these problems.

    Would love to have access to a higher level of technology but it is amazing. The battery life is only around 4 days at most so if that could be 7 days it would be amazing.
