Review on Accurate Home Blood Pressure Monitor - Automatic Upper Arm Cuff 8.7-15.7In, Large LCD Display & 120 Memory Sets - Device Bag & Batteries Included by Katie Ray

Seems very accurate. Cuff fits well and is large. Everytime you change batteries you need to program it although it works out of the box. It loses the stored history. Annoying to me is it talks to you although that's easy to shut off and maybe easy for some who can't hear because the screen doesn't light up. It uses 4 AAA batteries. They don't last long. Probably 40 cycles and they are dead. AC charger is available to order. 4 stars because of the batteries.
