I’ve been supporting Oura since it was a kickstarter. I had the version 3 and decided not to upgrade but since my spouse lost her ver 3 I gave her mine and ordered this.
If you’ve never had an Oura ring: this product is amazing. So comfortable, more so than a watch. The app is great, I’ve learned so much about sleep habits, what to do and not to do for sleep. Lovers of science will like this, you can literally experiment and see the exact results for yourself.
Accuracy: I would say this is 95% accurate. Again, I’ve been using this for about 5 years. So I’ve seen the accuracy improve IMMENSELY over the years. Version 4 is the best yet. Better than any other sleep tracker I’ve tried and I’ve tried a lot. The biggest inaccuracy is every now and then I’ll get up to pee in the middle of the night and it will think I woke up for the day. Sometimes it knows I just went to pee sometimes not. Since I noticed it, I take my ring off if I get up to go to the toilet and it fixes the issue—just don’t forget to put it back on!
Key info for consumers: the fit is slightly larger than the version 3. To be exact I would say the version 4 is about half a size larger. So the new size 7 for example, would be a size 7.5 on the old version 3 and older models.
The new size is great for me. My old ring was snug on my ring finger. So now I can wear the new one on my pointer finger and even middle finger depending on how hot it is. It all depends on the temperature outside due to our hands expanding/shrinking in heat/cold. Hot days I’ll wear on my ring finger, cold days I can wear on my index or middle finger.
Conclusion: I love the Oura ring. It’s more comfortable than an Apple Watch or a woop in my experience. Way, WAY more comfortable. It’s also very accurate and the info is extremely useful. It’s increased my understanding of sleep, the importance of exercise for sleep, and dare I say, made me a better person. Getting better sleep takes effort, and this is merely a tool to help you do that. Getting better sleep can 100% make you a better person and I speak from my own experience.

A really smart gift.
The Oura Ring 4 Sizing Kit makes the perfect gift for your loved ones who want an Oura Ring 4 but you may not know their Oura Ring 4 size.
Worked Great To Find My Oura Ring Size! Discount Was Automatically Applied To The Ring.
I was hesitant to buy this because I worried it would be complicated to apply the discount from buying the sizing kit to the ring, but it was completely automatic (I bought both through Amazon so I can't say it is the same anywhere else, but on Amazon it was automatically applied to my checkout)! I didn't have to do anything.The sizing kit works great! It came in a box with several different sizes from very small to very large (size 4 - size 15). The size you are wearing is on each band so you won't forget which size you are wearing. The size number raises up, as part of the same material of the ring, meaning it cannot fade off, and you will always know which size each ring is.I found the most comfortable fit and wore it for a few days to make sure it was snug but not uncomfortable. The ideal fingers for the Oura ring are the pointer, middle, or ring finger. If you are prone to swelling you could size it to your ring or pointer and if you have swelling, move it to your middle finger.It is good to buy the kit to be sure, but I will say that the size I bought is also my ring size. I am still happy I bought the sizing kit and didn't risk having to do a return if it were different (and it can be), and it didn't cost me anything once I bought the ring.If you know you want the Oura ring, don't hesitate to buy the kit, as you will get your money back when you buy the ring, and it will save you the hassle of a return.My daughter ended up taking the smaller rings and decorating them, so we got some use out of the extra rings, as well!
