Review on MCNNADI Fitness Tracker with Blood Pressure, Heart Rate, Oxygen Level, Temperature Monitoring & Sleep Tracking - Includes 4 Additional Straps. Customizable Face, Activity Tracking, Remote Camera Control, Waterproof Pedometer Watch by Jamal Gignilliat

Suits me! I love this fitness tracker and for the price I think it's worth every penny. Blood pressure, heart rate, blood oxygen and temperature worked well for me. I work in the medical field so I compared it to a $120 sphygmomanometer and found it to be 3 points up/systolic and 2 points down diastolic but for this price point and for a continuous monitor I think it isn't Deviation gives between 5 and 10 points is 100% acceptable. This watch is a guide and tells you when to see a doctor, and shouldn't replace a $100-$200 blood pressure or blood oxygen meter. If you want a hospital grade machine, you have to go to a medical health store/department and buy a $150 machine for blood pressure only, not for exercise and recreation, to the point of missing a head just to have it on her wrist to see - I schedule it for her. Highly recommended.
