    I have found the aura ring useful. It helps me recognize and validate how I feel, lol. It's been interesting watching the date and trends and understanding how my life choices affect my physical health. The fit has been a little challenging even though I went to the store and tried on the tester sizes first. I have large knuckles and thin fingers. I got my ring towards the end of summer and it fit rather snug at the time. Once the weather cooled off and possibly just changes in hormones, diet, and water retention, etc the ring became much looser and the heart rate wasn't being recorded consistently. I ordered some products online to help with the fit when it gets loose and that seems to be working pretty well. So, overall happy with the oura ring.

    I’m absolutely in love with my Oura Ring. It not only helps me track my sleep, but the platform has also given me great insights into my menstrual cycle and how it impacts my energy throughout the day. It has provided me with a clear view of my overall health, allowing me to make more informed decisions about my daily routine. It’s an investment that’s totally worth it!

    Love the Oura ring. Sets up pretty easily and the sleep and vitals tracking is amazing. The battery can last a week or so, which is awesome.

    I bought this for my dad and he absolutely loves it. He was using his phone before to calculate his steps but boy was he shocked by how many more steps he actually did when wearing this ring and leaving phone behind/charging/etc. It also tells him when to rest and his sleep - he just loves it. So happy as he is a hard person to buy for.

    Im in love with my oura ring. Hands down much better than an apple watch. I love tracking my sleep, and my active calories that im burning through the day. I mainly use this for sleep and tracking my periods, It lets me know exactly the date that i will be expecting it. Lots of people say that its bulky but it just another staple ring i wear everyday!

    I bought this for myself as a birthday present. I'm so glad I did! I wear it on my middle finger left hand. Love the rose gold. There is so much information to be gathered regarding daily life stats. Most that can be controlled. Really fascinating stuff.
