    The ring died after about a month. I went to bed it was charged and working, woke up it was dead. Contacted Oura support and they took about a week to respond. When they did I got a bunch of automated try this/try that and no recognition from them that the rind was defective. Still waiting to hear from them. Returning the ring, loved it at first now not a fan.

  • Do NOT buy an Oura 4 ring!

    I did some research and decided to get myself an Oura ring 4 for Christmas. At first I loved it. But about a month and a half afterwards it stopped syncing with the app daily. At that point it was unreturnable to Best Buy. So I contacted Oura. They admitted it was a defect and was under warranty. So they sent a replacement. I got a notice from UPS that the package was opened and product was missing and they then discarded the package. Honest to GOD! I can show anyone that message. I reported this back to Oura customer service and they told me they would investigate and get back to me. After MANY repeated attempts to get any response from Oura they have basically ghosted me.... Mu initial feeling was they had great customer service but my opinion has changed. I even showed them the message from UPS. I would think since THEY shipped it - they would have access to the same info... My next avenue is to try and contest things with the credit card company as Oura is a huge letdown.

    I really like the concept, however when I had the ring, I misplaced it several times and wasted time trying to find it. If my phone could hone into it like my phone to my AirTag… or if the ring would do a beep, that might help. I started getting anxiety over losing it, I found myself being occupied by the thought too much, I had return it.

    The quality is good and what you get for tech is good. BUT... you need to pay a SUBSCRIPTION for more than basic data. For $350 dollar ring, you still need to pay every month. NO THANK YOU. Get an Ultrahuman if you can. Oura sued them, so they are hard to find in the US.
