    I’ve been really happy with the Oura Ring so far! The fit was perfect thanks to the size guide — definitely recommend wearing the sizing ring for 24 hours before ordering to account for any finger swelling. The ring provides solid insights into your health and wellness, like sleep, recovery, and activity levels. Just keep in mind, you’ll need to figure out how to interpret and use the data in a way that works for you. Overall, a great tool if you’re into tracking your health more closely.

    Great product for health information on a daily basis. I can keep up with total steps,which is more accurate than my Apple Watch. Get sleep data, plus activity level, alone with information to let me know about any temp changes to alert me about potential infection.

    Once you get past the bulky feeling, the Oura Ring 4 really feels like a constant health advisor that's available at quick glance. It provides excellent feedback regarding sleep score, cardiovascular age and even has a new symptoms add-on that will try to catch sickness early! Would highly recommend!
