Oura Ring Gen3 Sizing Kit - Size Before You Buy the Oura Ring Gen3

I was on the fence for a while, but decided to splurge and buy myself an Oura ring. I wish I bought it sooner! I've been an apple watch wearer for many years, but wanted more insights as I've been on a health and wellness journey. The ring was annoying at first, but now I hardly think about it or feel it. It's light weight and not obtrusively thick. I strongly recommend getting the sizing kit first and wearing the sizer for a while to get a feel for the ring. I chose to size it to fit my left pointer finger. The battery life is insane! I only have to charge it every few days. The sensors on the 3 don't hurt or feel weird or anything. I always wondered how legit this thing was, and if they could really tell what was going on but sure enough I wore it for a small inpatient procedure and my ring told me something was greatly stressing my body and I needed to take it easy! It's wild how it just knows! I also love learning about my sleep score and what effects it.

The sizing kit has 2 x size 7 rings. The size 6 ring is actually a size 7. The kit is useless to me as I need to compare sizes 6 and 7. The box was sealed, so I believe it wasn’t tampered with and it’s a quality check issue. Now I have to reorder another kit, and hope for the best that i won’t have the same issue again.

Did not like the ring on finger for long period even though I wear a ring

Waste of money.. The ring is not available on Amazon, and they won't send it outside US

OURAリングを中古で購入することを検討していたため購入。新品だが、箱の状態がよくないものが多少安くなっていたので選んだ。 これがなくては指の太さがわからないため適切なサイズで注文するのは難しい。 中古などの最安値で購入して確認すればよいと思う。 長期間着用するようなものでもないのでおそらくほぼ汚れていない。 現在(令和7年7月)の4世代とは規格が違うし、そちらは一応公式サイトで無料でのサイジングキットが謳われているので新品で買うならそちらを見るべきだと思う。
