Review on 1.69'' Smart Watch for Men and Women: Fitness Tracker, Heart Rate 📱 Monitor, Blood Pressure & Oxygen Level, Pedometer - Compatible with iPhone, Samsung, Android Phones by Chris Thrower

Ridiculous. The pressure is not accurate at 20 points above and below compared to a medically calibrated cuff. Then the heart rate jumps everywhere. Started at 71 today, gradually went up to 84, then back to 71, then 111, then 46. Ridiculous. No wonder my doctor said I should buy an Apple. You really do get what you pay for. Save your money and don't buy this and certainly don't trust them to give you an accurate pulse!
