    The Oura ring is a fascinating device and the insights it provides into your health and well-being are very interesting and seem to be very accurate. The ring and application work very well and it is comfortable to wear. I’m glad that I picked one up.

  • A lot of Nice Features but questionable price

    Comfortable enough and syncs well with apple watch activities. Love that it calculates BMR and total calories burned. Paying for a monthly subscription is frustrating considering how expensive the device itself is & how limited/poor the included warranty. I’ve had it three weeks and it seems to be holding up well to a lot of handwashing and sanitizers. Please try the sizing kit first…you do have to wear it snugger than you would think to get consistent data!

    Very helpful and easy to track. Sizing was a little confusing but it is better to go with a little more room instead of a perfect fit as the fingers can swell over night and the ring constructs you.
