Not for SpO2 for COPD sufferers.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have COPD and I bought the ring for SpO2 readings. It turns out you only get one value daily. It is an average for when you are sleeping. This is now providing SpO2 at all. I have the Apple Watch 9 with SpO2. It is no longer available from Apple in the US due to a patent dispute. I was looking for a backup. Spent a lot of time with their tech support with no positive result. This may be good for others but it does not do me any goo. Additionally, the set counts are erratic. I compared to my Apple Watch and a pedometer. Not sure that is meaningful. Step counts are all over the low with different devices anyway. So this rating is just about SpO2.

Color fade
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I like what the oura ring does, the information it provides. But the rose gold color faded very quick and it was the most expensive choice.

Works well but I don’t recommend!
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I got this to track my sleep and it seemed to work really well, but after a few weeks of wearing it, my finger began to hurt really bad. I looked online and apparently that is very common with people who wear this ring. It has taken months before my finger has fully healed. I have no idea why it does it, but I finally got rid of it and won’t ever wear it again.

Tracked reading time as deep sleep cycle
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Feels cheap, doesn’t hold battery long enough, even put it on charger is a challenge, as you have to fit some pins into channels. Measured two hours of my reading as deep sleep.

Live up to your name or change it.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.After a promised birthday delivery date that you failed to complete, notice that a piece was in Stafford with Fedex to be delivered the next day that apparently disappeared, two more fruitless visits to the store and a "manager" who informed me bluntly that he could not issue a refund, we returned to the office only to spend another wasted hour on the phone with your service person. It was a horrible experience, It will take me some time to return to Best Buy for anything, Live up to your name or change it.

Garbage
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Broke within three weeks for my wife, mine broke within two weeks. Returned it. I also read this is a common occurrence with this ring. Makes no sense spending this much on a ring and it doesn’t last.

Customer service Sucks!!!!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The product is amazing, but the customer service at best buy is the worst. I don’t think I will ever purchase another thing from them again. I would recommend this item to everyone, but purchase from a different retailer.
