The ring is very attractive and I will enjoy wearing it with everything. The middle looked like brushed silver tone in the listing photos but it is actually white cloisone. There are 5 little rhinestone stars around it. Dressy but also casual. I've loaded the app and no surprises. No requests for credit cards like some I have tried. I did my first measurements and they all seem right, with the exception of BP which always seems low compared with my Omron BP monitor. Overall a great purchase

Runs small, I'm not able to wear it on the fingers I had planned, but they replaced it at the same price. Measurements are not matching my galaxy watch, blood pressure cuff and O2 monitor. BP top number is always too low but bottom number is close. Sleep doesn't record during daytime hours. Nor does it match my watch data. Heart rate, sleep and steps are automatically recorded. For BP, O2, HRV, and Stress - open the app and push a button individually. I really like the app. Looks great and easy to read. If close but not accurate works for you then buy it. However if you need really accurate measurements, I wouldn't recommend. Battery lasts several days, perhaps 4 ish. I'm quite sure the ring I got was already used but it was really a low price, so for now I'm using it as it works fine.

Absolutely love this ring. The app is free and easy to use, tracks blood pressure, heart rate , blood oxygen levels and sleep! Great battery life and very comfortable.

The ring is beautiful and works well! It took me a minute to get it linked to the app but since it’s established I have had zero problems. It’s waterproof, long battery life and easy to charge. The heart rate, blood pressure, HRV, sleep and work out monitoring is excellent and accurate. I see no future problems for durability as it’s well crafted. REVIEW UPDATE: no longer charging and lost stones. Doesn’t track sleep anymore and the battery dies quickly

The media could not be loaded. Love this smart ring for the price. Works as intended. Battery life is pretty good. Lasts about 3 days. Tasks my steps great. True to size. The diamonds have almost all fallen out. You can wear it in any body of water without fear of breaking it. Overall a great buy.
