浮腫みが気になる
歩数や心拍のデータを取りたくて、腕時計タイプのものを長く使っていました。腕時計が嫌いなので指なら邪魔にならないかと思い買いました。サイズを決めるのが難しく、浮腫むことを想定してゆるめで購入しました。<マイナスポイント>・このリングをすることで浮腫む。普段指輪ではさほど浮腫まないのですが…。・腕よりは邪魔にならないが、指の違和感はまあまあある。・リングが分厚いので指が太く見える。・サブスクリプションが高い<プラスポイント>・腕時計よりは邪魔にならない・アプリが見やすい・取れるデータとアドバイスが良い・充電機器がシンプルでスタイリッシュ最終的には腕時計タイプのものに戻しました。最新版のものはリングがもっと薄くなっているそうなので、試すなら一番新しい方を使った方がいいと思う。

So accurate! Especially for the girls!!
I’m so pleased with my Oura ring! I did my research prior to buying this one and from watching people compare and test them against each other. The Oura ring would outshine them with their accuracy.It’s incredibly accurate and for the women out there it has done such a great job in predicting my menstrual cycles I don’t ever get surprised anymore. My only gripe is the fact that there is a monthly subscription charge for the app but I can look past it for now because it’s about the same as a cup of coffee. I also understand that the app is always updating and offering newer insights so I assume the cost goes towards maintaining and improving it.Although there are other brands selling at a lower price point and without a monthly membership, I would say I’m still very pleased with my purchase and I feel much more assured that it’s accuracy and insights makes the extra cost worth it

Loving my OURA
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 :)

Great
The ring is great and fits well. The Gold Color is different from the picture, the color is ok but looks very fake gold color. Delivery did not arrived as promised.
