Title: Loving my OURA
Review: Using the OURA ring for 4 months nearly – so far so good, zero complains – my Ultrahuman ring had an interesting feature of showing brain age – which I miss in this ring , but the major issue with ultrahuman was within 2/3 months of purchase the ring stopped connecting with the app , started having post firmware upgrade issues etc – though their customer care in India was fab and tried their best to support but had to return that right and post that I got OURA and it had atleast 2 upgrades (app + ring ) in last 4 months – but nothing stopped it , another delinging feature OURA is giving 6 months extended subscription to all early adopters in India so I would suggest people go for it and have ur ring. By the way mine is size 6 and golden , looks bit worn in 4 month with craches etc but that’s fine and unavoidable as we work / exercise all the time 🙂

Title: Beware
Review: Product failed after a month. Company is sending replacement. No clue about the problem or issue. Ring not connecting to app and charger shows white light and then off. Think before buying. Costs a lot and issues are still there

Title: Sensitive and accurate
Review: The sleep review is excellent. I have problems with sleep and the ring is really helping me. One problem is it doesn’t track walking on the treadmill if you keep your hands on the bar but that’s an easy fix. Sensitivity is good. The charge stays for over 7 days.

Title: Excellent product reviewing after 9 days
Review: I wear the Size 11 Black Oura Ring 4 on my index finger. Fitbit models force a heavy, distracting screen onto your wrist during sleep. Samsung Galaxy Ring and Ultrahuman Air rely on protruding epoxy sensor domes that press into your skin. Oura Ring 4 eliminates these hardware flaws with a fully titanium inner shell and sensors recessed by 0.3mm. It weighs 5 grams and captures continuous, high-fidelity physiological data.

Title: I love it!
Review: I don’t like wearing wrist watches, so having a smart ring is PERFECT for me! I love how durable it is, it’s easy to clean, and the app that comes with it is GREAT! The tracking on this thing is flawless and it uses light sensors to track my vitals, so it doesn’t even feel like a smart device, just a regular ring! It also charges very quickly, so if I’m using the bathroom or taking a shower at home, I just pop it on the charger for 10-15 minutes and it’s good for a few days! I only do it daily just to establish a good routine, and I have forgotten before and let the battery get low, but still haven’t had the power die on me yet!
