Review on MorePro SpO2 Blood Oxygen Blood Pressure Heart Rate Monitor: Waterproof Smart Watch for Android iOS Women Men (Green) by Greg Shorter

if this applies to all or all watches of this brand. I bought this watch specifically for an oxygen saturation monitor, a heart rate monitor and most importantly a blood pressure monitor. The first two were generally accurate (you can easily measure and calculate your heart rate by observing the second hand of a watch and comparing the readings of the watches). The oxygen monitor proved to be accurate as I got the exact same readings I normally get. when I go to the clinic. But for blood pressure readings, I had to rely on my pharmacist's caveat: She specifically said that wrist blood pressure readings generally differ by about 5 points, but sometimes by as much as 10 points. So I wasn't too worried. (If it read 111/78 I could certainly add 5 points or even 10 points and feel like my totals at the pharmacy were close to accurate. A full 20+ points. That was a level of inaccuracy that I could do honestly didn't pay and have returned it.ANY advice on a more accurate make or model is MORE appreciated!
