Review on Kirlor Fitness Tracker: Colorful Screen Smart Bracelet with Heart Rate Blood Pressure Monitor and Bluetooth for Android & iOS by Mark Gancio

First bought for my wife she is happy) After buying 3 more for our daughters and the last one for myself. All measurements look correct, only blood pressure is doubtful. Before measuring, you need to set the limits of your actual blood pressure in the application, and the system will only measure pressure within these limits, even if your pressure is above or below the limits , it does not show the actual one.
