    Wanted to gift the ring but was unsure of what size was needed. This is a perfect solution. You buy the sizing kit and get a coupon for the amount of the kit. It essentially costs nothing and you ensure you get the right size.

    Excelent. I got it for my kid, and he loves it. Sleeps with it all nights and gets him the right information. He later uses the data to improve his gym routine as well.

    Excellent metrics, definitely the best ring out there. The app monthly fee is also affordable. Wish it registered activities without manual trigger, but it’s much more accurate than other rings so it’s worth it.

    Good product, however, without mothly subscription it's useless. So, if you are ready to throw another $7 per month, then it's not a bad choice
