    I like the look of the ring, but struggle with the size. I did wear the sizing kit ring for 24 hours as instructed and ordered the proper size, but I find that my finger changes drastically during the day, and especially at night, so that at times my ring is too tight or too loose. I am still learning to decipher the information from my ring on the app, but it seems quite detailed.

    Great fitness tracker. I use it more for recovery and sleep metrics. The only thing I don’t like is the battery life is very short.

    I LOVE my Oura ring. After wearing it for 3 months now it tells me my body clock and tells me I am a morning person. (Which is a surprise), along with tracking your stress. It’s amazing what it tell you about your body and such.
