    I ended up returning the ring. The ring was too bulky. I had it on my ring finger and it was bruising my middle finger. I liked how’s it could monitor my heart rate and sleep etc. just was not happy with how it fit.

    I'm really enjoying this device, it does get a little heavy and "full" feeling at times, but I just take it off for a bit of breathing room. The data is great and I can't wait to see what more I learn from it as time goes on.

    His ha been beneficial in tracking several health factors through the day. The only drawback is how tight the ring needs to be to read well, also causes that sweat band/discoloration on your finger.
