    The product is good but the store only has limited amounts I needed a size 12 or 13. They only had size 11. I purchased it and have regretted it ever since. Also note there is a year or monthly fee. Yearly $69.00 which was not really realized at time of purchase. I have since cancelled this service. Use it as a pinky ring!

    The ring looked nice at first and the design is not bad, but after just a couple of weeks the color changed and it started to look worn out. It also got many scratches very quickly, even though I was careful with it. Unfortunately, the quality didn’t meet my expectations.

    Ivv officially have had this on for 1 month and I think It is completely awesome. It tracks sleep time, I believe to be accurate.. it will be me how long it took me to sleep. Which is something I was most excited to use.

    I am a big fan of the Oura Ring and the version 4 improves upon an already great product. I do feel the data is more reliable in this latest version and the ring look much better. The finish seems to have some durability issues.

    I absolutely love this. I’ve had it a couple of months now. So not an instant review like most are. When I knew it really was what it said it was. Was when I got sick. Do you know it knew I was sick before I even had symptoms. I’ve purchased a lot of things in my life. However, I have to say this is in my top 5 best buys, no pun intended (I purchased it at Best Buy).
