Review on 💧 Waterproof Fitness Tracker with Blood Pressure, Heart Rate, and Oxygen Monitoring, Sleep & Activity Tracker, Pedometer Watch for Men and Women by Brian Malith

Love the size and the soft silicone strap. I haven't checked the accuracy of the sensors yet. I am mainly interested in the oxygen sensor. Battery life is decent, maybe a week. The display is minimal with a very low resolution, good enough to show the time. Much better application on phone, easy to install. I don't like the fact that it's not a touchscreen. Control is via a touch button at the bottom, so you'll have to scroll until you get the feature you want. Bottom line, still good value for money considering the number of measurements, as long as they are accurate.
