    I was super excited about getting my Oura ring but could not handle the size. All of the vitals were super cool and accurate. If they made a smaller more feminine version I would buy again. It just looked like I was wearing a nut on my hand so I returned it

    The perfect gift for my girlfriend. I hear about her stats on the daily now and I look forward to it because she doesn't know it but it shows how much she appreciates it without having to say it and I cherish those moments.

    For starters this was my first “smart” ring. I managed to find a comfortable size and chose the stealth model. First thing that put me off from it was the monthly subscription fee (which can be paid annually if one chooses) but this I blame myself for given I did not put in my due diligence in researching more about it. The other, and bigger issue I had with it was it seemed like an unfinished product. Rings are supposed to be smooth correct..well one side was smooth but the other was far from it. You could feel the lip protruding from that side and when you ran your finger across it, it felt like metal that was not deburred . This meant anytime I put my hand in my pocket, I would meet with some resistance and for a $400 piece of jewely, this is not acceptable for me.

    The gentleman who assisted me was very helpful when deciding which color and size ring to purchase. I am really enjoying my Oura Ring, and would highly recommend to anyone looking to get a better understanding of their overall health.

    It is definitely better than a sporty Apple Watch. I get lots of compliments on how it looks, people think it’s my wedding band lol. I stacked it with two diamond bands and it looks great.

  • Great but not worth the monthly subscription cost

    I like the ring; however, the cost you pay along with the monthly subscription is not worth it. If you have an Apple Watch, you are basically paying a monthly subscription for the additional data that is nice to have, but not worth the cost.
