Review on Black Jiandi 2-in-1 Smart Watch with Heart Rate Monitor, SPO2 Blood Oxygen Monitor Chest Strap, Fitness Tracker with Blood Pressure Wrist Band, HRV Health Sleep, Calorie Counter and Activity Tracker by Lisa Fernandez

Connected directly to my iPhone after installing the app. Integrated directly into Apple Health so my document can also see the data. Lots of data collected on the first night of sleep. I'm getting used to it, but so far I like it, especially for such a price. It matches my other spO2 monitors exactly (I wore all 3 at the same time to compare) and the heart rate seemed to update faster than my other 2 monitors. My blood pressure cuff didn't work today so I couldn't compare it to this blood pressure cuff, but the readings seem to match my normal readings on my cuff. Very happy to see the long term data it brings me. The strap is good but I feel like I'm between the adjustment holes so I'll look for another strap if I can find one.
