Must Purchase if Looking to Monitor Health
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been really impressed with the Oura Ring. It tracks my health in a very advanced and detailed way, especially sleep, recovery, and overall readiness. One of the best features is how accurately it can predict when I’m about to get sick. I often get early warnings before I even feel symptoms. It’s comfortable to wear, easy to use, and the insights feel genuinely useful rather than overwhelming. If you’re serious about understanding your health and catching issues early, this ring is absolutely worth it.

Great
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.So cute I use it for pregnancy but it’s a pretty bulky ring and if your fingers swell, I wouldn’t recommend this but overall it’s amazing. It picks up everything that you need plus more.

JUST BUY IT...
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.After hearing about the Oura ring and all the data it can collect through just being placed on your finger, I was instantly interested. Originally, I was most interested in their partnership with Natural Cycles because I have been on birth control most of my life. I got pregnant with my daughter pretty quickly and as soon as she was born 2 years ago, I got back on birth control.. because, lets be honest ladies, I don't trust my husband when it comes to that... My birthcontrol will be expiring in the next year, so my hope is my ring will have enough data to help me use the natural cycle subscription to track my cycles and continue to prevent pregnancy. I am also an advance practicing nurse that takes pride in my health through weight loss, nutrition, sleep habits and so much more. This ring has helped advance my skills of understanding my own body and habits and my own health. I will be using this ring for the rest of my life.

Amazing
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is ring is the absolute best purchase I have ever made. It does so many things health wise and helps keep up with certain things for me. Recently I got sick and my ring told me something was straining my body the day before I was sick. The battery life is also amazing and that is a plus and it charges super quick. Its also very easy to set up when you first get it. This thing truly works and I would buy it again in a heartbeat.
