    I transionionef ftom the Oura # 3 whi h was perfect. I mow have the Oura ring 4 , love the impressive new features ! I chose the gold. The only problem gor me is the sizing . My 3 ring was a 7 fit perecy. I had to size up to an size 8 and still the fot is very snug on my mostly slender petite hands. MyOura Ring 3 had a more acommadsging shape. I find myself having to wet my fingers to remove the ring.

    I waited a long time to buy a ring like this because I wasn't sure it would do what I needed to do. Once I got used to it it was great! Now I know how well I sleep, how many calories I'm burning, my heart rate at any given time, my oxygen saturation percentage. And most of the time I don't even know I'm wearing it.

    Love this ring, tracks sleep, workouts, walking, and even tells me when I am starting to get sick. Only removed one star because it scratches extremely easily when weight lifting and I recommend that they sell some type of guard for us active gym people lol

    The Oura Ring 4 is an excellent choice if your priority is sleep tracking, recovery, and overall wellness rather than hardcore fitness tracking. It’s sleek, comfortable, and packed with meaningful insights that can actually improve your daily habits.

  • The 'Best' of the 'Best' ... the Oura Ring Rocks !

    Absolutely love the Oura Ring ... wearing it is comforting knowing how accurately it is reading your vitals ... while going about your daily activities or working out seriously to achieve body building results. Breathing and sleeping monitoring also is a plus ... as well as cardiac readings being recorded. The Oura Ring is one of the 'BEST' decisions I have ever made ... it actually suggests ways to improve your behavior and your health after the Oura Ring becomes familiar with you and your daily habits. Yes, I can only hope to encourage more people to purchase this exciting, innovative item ... and I am sure my enthusiasm about the Oura Ring will be shared by all !
