## Customer Reviews

### ⭐⭐⭐⭐⭐ dying battery render the ring useless, free replacement seamlessly provided
*by R***U on 26 August 2025*

Product works as expected and is hepful.After 7 months of usage battery is dying, resisiting less than one day after full charged. I contacted the seller, and free replacement arrived in couple of days, no need to return the mafunctioning one. As such, a one star reviewe turned into a 5 stars.

### ⭐⭐⭐⭐⭐ Life changing if you’re willing to put the work in
*by K***O on 22 June 2025*

I’ve had it for a month now and I can say it really keeps me on track not necessarily health and fitness but more habits and trends. I think everyone can benefit from it. It came neatly packaged and sealed 100% new and after wearing every day I definitely have a lot of small scratches (and I take it off for showering doing dishes etc) but not visible to the normal eye

### ⭐ Waste of money!
*by M***S on 27 September 2025*

Total waste of money! Zero after sales service and their system is compromised.Nothing against the seller but the issue I have is with Oura. My card details were leaked after paying for the membership and there is no support at all from oura neither is it very easy to speak to a human and get a resolution. I am stuck with a 1200 AED useless piece of junk
