    It’s well worth the price I’m a 56 year ole OTR driver who doesn’t get normal meals, sleep schedules or stress free days due to customers and traffic so it’s nice being able to see what I need to focus on more during my hectic travels

    after purchased it for me, in another week I've got another to my wife, I love the app and all features, being able to monitor my sleep and many other things. I'm happy with it despite being pricey.

    I love Oura - this is my 3rd- Each generation adds new and amazing features to allow you to review and understand health metrics. I believe that this hugely contributes to my overall health. Comes in different shades and materials. Can be a bit problematic with no half sizes, so may need to use different finger. Check your sizing first. A wonderful gift for you or a loved one.

    I love this ring! It’s definitely a bit on the pricey side, but I much prefer it’s features to the fit bit & it’s look to the Apple Watch. It’s aesthetic and comfortable AND shares all the data I was looking for. It’s brought great insight to my routines, especially sleep!

    Seems to be a good product. I like that the battery lasts 5-7 days and I can wear it in the shower and swimming. It did take some time to get used to wearing it! Added a cheap mini band to dress it up!
