  • So much data that I didn’t know I wanted to know🤣
Color: Petal Size: 7
Oura rings are the best! I recently gave my original gen 4 to my niece and purchased the petal in 2 sizes small as I have lost weight. The sleep tracking is on point! Same as the stress tracking! Check my sleep data and it is spot on! If you want to know just about everything you could know about your body this is a definite must have! Super comfortable and the battery life is outstanding! No vibration no screens! Just wear it and check the app when you want! I can’t imagine my day and nights without now! So far the ceramic seems far more durable than the original shiny titanium and it feels smooth and comfortable on the fingers next to the one I wear my ring on. I love that the data lives on the ring then connects to the app when you open it. Data seems super accurate to how I am feeling! ... show more

  • Wellness ring
Color: Petal Size: 9
I decided to get the Oura Ring because I wanted a health tracker that felt effortless and elegant. I started looking for a way to really understand my body — not just count steps or calories, but actually see how my sleep, stress, and energy connected. Setting it up was super simple — you just connect it to the Oura app, select your goals, and it starts tracking everything from your sleep quality and recovery to your activity levels and cycle patterns. What I love most is how it gives me personalized insights instead of just numbers. once I synced it with the app, it started giving me insights that actually made sense: how well I was recovering, how my hormones and cycle affected my sleep, even when my body needed to slow down. I absolutely love it. The battery life is almost 7 days I wore it 24/7. But is a very nice wellness tool. ... show more

  • The Best Oura Ring Yet!
Color: Tide Size: 10
This is my third Aura ring. I purchased the first in 2021. Oura gets better and better, but the Gen 4 ceramic is by far my favorite! It’s light weight and more comfortable than my titanium Gen 3. I love that they did away with the nubs inside the ring. I did go down a size in the Gen 4, so be sure to order the new sizing kit! The ring’s ceramic finish is very glossy and clean looking. The pale blue compliments my brown skin and my aquamarine wedding ring. ... show more

  • Love it! Recommend it!
Color: Cloud Size: 6
Definitely love it so much! You can track all your body! How was your sleep and how much calories did you burn! But I love the most is the stress level! Is so fantastic to me! It’s show me the stress level and also give some comments to it! An example, ones I had a hard time with my toddler and it showed me the massage that sometimes we can get a stressful situation from someone we love, but today I was eating pizza and felt so guilty about it, and in the app it’s showed me that I had stress and comment was “ something we can get a stress from something we eat or drink, I was shocked! Now my husband wants it too :) definitely recommend to track your body, easy to use, you need to charge ones in a while, perfect for me! ... show more

  • Love this
Color: Petal Size: 11
First time Oura ring user, absolutely love it, I’m only 48hrs in and I have no complaints.. Well worth the price in my opinion I normally wear a size 8, thankfully I went best buy and was able to actually check my Oura ring size with the kit they have out. Decided to go with size 11, and it’s super comfy. ... show more

  • They brought a used ring!
Color: Cloud Size: 7
When I pay the full price for a product, I expect to receive it in proper condition and quality! But why did the manufacturer send me an item that was previously opened? This product was meant to be a gift, yet the box arrived damaged and sealed with regular tape! What kind of disrespect is this toward customers? How can a used or previously opened item be sold for $499? You can clearly see torn labels and knife marks from when the box was opened before. ... show more

  • Packs a tiny punch in a ring
Color: Cloud Size: 4
I was a little skeptical at first because they always have new tech that claim they track sleep, activity, and stress. This one is a little different. It does a lot for a small ring. It connects easily and actually is durable. It’s also waterproof too (I accidentally got it real wet when washing my hands). You do have a to let it track for week before it starts tracking daytime stress. ... show more

  • Exceeded expectations
Color: Tide Size: 10
I was a little unsure how much incremental value there was in having this ring and an Apple Watch. I have been pleasantly surprised. The ring offers so much more detailed and customized information. It adjusts to you and sets customized goals each day. The app is super user friendly and connected perfectly with my ring at set up. The ring itself is aesthetically pleasing and comfortable to wear. Battery life is amazing. Not sure if the step count is entirely accurate as it is usually behind what my watch says. But that is a minor complaint. ... show more
