    The Oura ring has a good hardware and great software. Might benefit from some sort of tracker. I keep misplacing mine.

    I thought it was silly to spend this much money on one of these but I really wanted to track my sleep and temperature and knew this would be a little more accurate than a smart watch. What’s nice about this is I also have a Garmin watch so whenever one is charging I have the other for a back up.

    I love my oura ring, it gives great health insights. Definitely size up, so you dont have to worry about finger swelling while sleeping. It also takes awhile for it to configure to your body, so you wont have a lot of insights right away. However, definitely worth the wait!
