Oura Ring 4 - Rose Gold - Size 10 - Smart Wearable | Size First with Oura 4 Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days Battery Life : desertcart.ae: Electronics

Review: Very good ring, apps, afterservice - I bought in Apr-25 (with Salama 1yr extra warranty). I have been using this ring a everyday and never give me issues. However, these last couple of day, it started to lose connection when i am outside, and battery seems to be very quick charge. Contacted the support thru app, and got replacement in mere minutes. Very good after service. Ring itself is very good at tracking sleep, stress level, and help me plan my day. The heart rate is same as my sport band type hrm. The app is very good, able to sync with strava, google health. If any suggestion i would make, is for Oura to allow the notes for daily supplements to carry over. I have supplements around same time, everyday. I would recommend the ring for the after service, apps - and that it comes in a ring package, so i can wear my watches without feeling dumb :)
Review: New Ring - My Oura Ring arrived in perfect condition, the box was closed and the ring is new, was very easy to create and account in the app, I got one month free subscription as advertised, I was so worry about the reviews and at the end everything works great. Love the ring colour.

However, these last couple of day, it started to lose connection when i am outside, and battery seems to be very quick charge. Contacted the support thru app, and got replacement in mere minutes. Very good after service. Ring itself is very good at tracking sleep, stress level, and help me plan my day. The heart rate is same as my sport band type hrm.

### ⭐⭐⭐⭐⭐ New Ring
*by A***A on 27 May 2026*

My Oura Ring arrived in perfect condition, the box was closed and the ring is new, was very easy to create and account in the app, I got one month free subscription as advertised, I was so worry about the reviews and at the end everything works great. Love the ring colour.

### ⭐ Do not waste your time and money with this product
*by G***E on 19 May 2026*

Subscription onboarding flow is terrible - took 30 minutes - still issue appears. "Something went wrong" message is the worst type of UI error handling company can imagine. Sizes brackets are ridiculous - one is small, next is large. And nothing in between. Rings itself is pretty much useless - there are much more advanced products on the market.
