Questions & Answers (37)
Q: Does the black get scuffed or scratched easily? (2 answers)
A: I have the 3 in black have not had it a year and it is all scratched up. It looks horrible. I hope the 4 is made better- A: You get the membership for the first month for free just for buying the ring. If you choose not to renew you only are able to access sleep, readiness, and activity scores. You won’t get access to the symptom radar, stress insights or other features. I’m not even sure if without the membership if you can access the details of your sleep or it’s just a score. Hope this helps!
- A: I read one review - can't remember where now, maybe thewirecutter.com - that said it hurt the reviewer's hand to wear while lifting, but was recommended otherwise. Regarding scratch protection, there are a ton of silicon covers available from third parties.
Q: What finger do you need to wear the ring on. (2 answers)
A: The website says that it can be worn on any finger but for the most accurate data, wear it on your pointer, middle, or ring finger of either hand.Q: what is the difference in Ora Ring 3 vs 4? (1 answers)
A: Longer battery life, a bit thinner and more comfortable. I find it harder to keep in the correct orientation without the sensors on the inside.- A: Because every single thing is “known by the state of California” to cause cancer. In this case it is likely either a microchip or epoxy.
Q: Can you get sized at any Best Buy store? Also, can you purchase this with a HSA account? (1 answers)
A: Not sure about sizing at Best Buy, I ordered a sizer and it came In 2 days. It was nice to be able to wear the sizer around for a couple days to ensure correct size. The oura website says HSA/FSA eligibleQ: Can this be worn while swimming? (2 answers)
A: Yes the Oura ring is water proof, they actually have swimming listed under their activities list for workouts on the app
