    The Oura is such a great product for an everyday use but the only thing that I don’t like or feel comfortable is when at night time I get swollen my ring gets stuck and it discomfort. I even purchased a one size bigger and it doesn’t work at all.

    Have had the ring a couple weeks and am just now fully up and running with established "base lines". Enjoy the technology and App. My only negative is the material of the ring itself. I got the matte black Oura 4 and the material/metal is quite soft and susceptible to scratching. After wearing mine outdoors doing some yard work it got pretty scratched up. Since you want it to measure activity, you'd think they'd use more durable materials considering the price of the product. Found out after the fact there are "ring covers" although that seems to defeat the purpose of the rings design and finish if you're going to hide it under a cover.

    I have had TWO rings in less than a year because this product is simply trash. The first ring I had for 6 months and it went belly up and wouldn't connect to my phone so I couldn't access my data, so I was simply left with an ugly ring. Then I contacted customer support and they were all bots and never heard from a real person. So I returned that ring. I got another because I was thinking hmm probably just a faulty one. NOPE! The life span of these rings is about 6 months. Now my ring wont hold a charge for more than 18 hours. PS this company is not backed by the better business burrow Put simply : The customer service is the bottom of the barrel and for those who say it has an impressive battery life. I THINK NOT! There are other smart ring options that have a much better price point! Look into those, and if you are getting bullied into using an Oura ring by author company (a woman's health app). Look into the tech options they provide like the bracelet or thermometer. PS ladies don't Gas light yourself, it is UGLY

    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.

    No issues. Does exactly what it says it tracks using the app. I wash my hands with it on with no issues and doesn’t cause any rashes. I have the silver, shows mild wear but only if you look close. Happy with my purchase overall
