This extremely efficient machine is so easy to use. It comes with full instructions, a great carry case and a warranty! It has the capability of storing the readings of two separate people. I personally do not have high blood pressure but I do keep a check on it regularly because of my family history.
One of my tenants takes medication for high blood pressure and is required to take his at least once a day. He loved the added feature of the storage of prior days readings. The unit is super light and very high tech. The screen display is larger so it's easier to read.

CardioTech products by Ozeri offer clinically proven technology and are used by physicians and hospitals around the world. Compact, portable and simple to use, the CardioTech Premium Series BP3T Blood Pressure Monitor is an advanced 2-user arm-cuff monitor powered by a state-of-the-art CPU that utilizes a double pulse detection algorithm to enhance pulse wave detection, thereby improving accuracy. Unlike traditional blood pressure monitors that inflate to 170 mmHg or higher by default, the CardioTech BP3T utilizes MWI (Measure While Inflate), a dynamic measurement technology that varies the inflation process according to real-time blood pressure detection to reduce measurement time and increase user comfort. Featuring a Blue LCD with LED backlight, touch sensitive buttons, and a slider switch for easy user selection, the CardioTech BP3T Blood Pressure Monitor stores up to 120 blood pressure readings (60 x 2 users) with date and time memory recall. The CardioTech BP3T automatically classifies each reading according to World Health Organization hypertension guidelines with an intelligent graphical display. It also calculates average blood pressure based on the last 3 readings, and detects irregular heartbeat (Arrhythmia) for an improved understanding of your heart's health. Backed by a 5 year warranty, the Ozeri CardioTech Blood Pressure Monitor ships with 4 AAA batteries (included), a medium sized arm cuff included (8.7"-14.2"/ 22-36cm) a carrying bag and user manual.
I really loved the ease of operation with a one button push. It also detects any irregularity in heart beat and tells you if your pressure is too high. I was very pleased with this product!
