Love My Ring - Scratches Easily Though
I purchased the Oura ring a few weeks ago and love the insights that it produces. I wore the sizing kit for a few days and watched plenty of videos on how to select the correct size since I was in between 2 sizes. I chose the smaller size and so thankful that I did because the Oura ring seems to fit a little larger compared to the plastic sizing kit. The ring itself is very comfortable to wear and I hardly notice it on my finger anymore. The battery life is fantastic. You are recommended to charge it a little each day, for example when you shower. My Oura ring hardly needs a charge and is pretty much always full. I am excited to get more insights into my health the more I wear the ring. The ring was very quick and easy to set up via the app too. I marked the ring 4 stars instead of 5 purely because the ring scratches very easily. You are advised to not wear the ring next to other jewellery, which I have not been doing, but it seems that somehow I have badly scratched my ring already. And the worst scratches appeared in the first few days. I don't think anyone else will notice the scratches, but I can see them.

What worth the money?
My partner is amazed at the ring really impressed with it.
Spook, 35 - 44
Great features.
I’ve been wearing for almost a month and absolutely love it. The charge is excellent and is a lot comfier than a tracker watch. The app is really easy to navigate.
BLS, 25 - 34
Love it!!
Bought this just under a month ago and I swear by it. Great for tracking sleep and menstrual cycles (don’t have to pay for natural cycles app, oura does it alone perfectly) would definitely recommend buying the ring sizer. Size down if between two sizes!! Battery lasts over a week for me and doesn’t take long to charge. Would recommend buying a protective case as they scratch easily but these are found cheap online.

Hello Anne
I can advise the following for: Oura Ring 4 Bluetooth Smart Ring Black - 11
To find your Oura Ring size, you must use the official Oura Ring 4 Sizing Kit because Oura sizes are unique and differ from standard jewelry sizes; wear the plastic sizer for at least 24 hours, including sleep, to account for finger swelling and find a snug but comfortable fit that doesn't rotate easily, typically on your middle or ring finger, using the included coupon to purchase the actual ring.

Hi there,
The Oura Ring 4 Bluetooth Smart Ring Black - 5 can be worn on any finger of either hand. For the best signal quality, it is recommended to wear it on your index finger as this is where you have larger blood vessels, which help optimise pulse monitoring. The middle or ring finger are also suitable

The Oura Ring 4 can't directly measure blood sugar on its own; it can, however, integrate with a separate device to display your glucose levels in the Oura app.
