    I’ve been wanting one for quite some time and with the arrival of the 5 discounting the 4, I took advantage and purchased. It’s only been a few weeks so far but I love it. I got an 11 at first and had to exchange for a 10 - the customer service was wonderful as well.

    My smart ring fits my finger perfectly. I was concerned about washing my hands with it on but it is waterproof so it is not damaged. I've also worn it in the shower and it still works perfectly!! I do wish it had more 3rd party apps I could use with the data it collects. Overall I'm happy with my purchase.

    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.

    The concept of the ring great. Unfortunately, I had to return it. The ring was in the way of working out ( holding kettlebells and/or dumbbells) and it was very heavy on my pointer finger
