    I find the data the ring collects very insightful, however, the ring does scratch easily. I would recommend a cover for when using it while weight lifting.

    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.
