Gabriel Considine Stunning price for a hard-working health ring, and no maintenance fees. iβve never had one last as long as a year, so iβm hopeful that this one will. so far it keeps good and accurate track of my steps, my sleep, my blood pressure, and my oxygenation. i had a far more expensive one that added glucose monitoring, but that was inaccurate at $57. $15 is an amazing price for the functionality of this clever ring! i think the sizing is about three sizes small so be cautious

Karina Stracke Okay

Marcos Abshire Very good, it takes all measurements accurately, except for the calorie consumption on exercise bikes, but otherwise it's quite impressive for the price. BUY TWO SIZES BIGGER THAN YOUR FINGER SIZE.
