Review: Love my ring! Sizing is different in Oura 4 than it was for previous versions. - In the previous versions of the Oura ring, I wore a size 11. The size 10, version four is perfect. I did have a problem with the discount from desertcart. When I purchased the ring sizing system for $10 and figured out the size I needed to purchase, I didn’t receive $10 credit towards the purchase as advertised. Just know if you purchased it through desertcart you may have that issue even though I bought both items from the same product link. My initial ring was a silver one and I am very happy with the gold except the scratches show up so much more on the gold color ring than they ever did on the silver! The Charge last a long time and I had gotten down to about two days per charge for my previous version. Since day, one of having an Oura ring, I have worn it twenty four seven except for the one night a week when I spend thirty minutes to forty five minutes charging it. I wear it for sleep, shower, dress up, casual, work, home, gardening, working on a car… I can do anything wearing this ring and continue to wear it all the time!
Review: Love this ring - I bought this ring a full year ago. I have loved the features that come with it. It’s worth the money for the ring and the monthly subscription, which is only $5 for the monthly. And it does so much. I recently needed a replacement and it was the easiest process ever. Overall, the pros have vastly outweighed the one con that I’ve had with it, and that was the recent battery issue after a year of having and it wearing it every single day.

### ⭐ Disappointed, not durable and not worth the money 🙁
*by H***6 on November 29, 2024*

I have 3 relatives with the gen 3 and they loved it. Since it had such good reviews I splurged on the newest gen 4 and got the gold one. The gold is a brassy color and my sisters gen 3 is a better gold. I noticed scratches on mine right away and bought a silicone cover. I worn that for a few weeks and the past 2 weeks have been wearing it without and it has rubbed off in places and is silver underneath. I have also been sick for the past week and have had a fever and the ring showed a little bit of difference but still had I had a relatively good nights rest even while walking up coughing several times a night. Could the 3 be a better ring? I had such high hopes from the rave reviews from relatives. When I took the walking test it said my cardio capacity is at peak which is weird because I don’t exercise. My daughter who just ran a half marathon has a lower capacity than me and she is a runner. What am I missing here? The ring is not durable and looks cheap and scratched up, the info is not accurate and I paid $500 for this plus $7 a month? Going to contact the company because I think I. got a lemon. I waited a month to give it a fair chance but now the return window is closed.
