This is a great high quality blood pressure monitor I have tried different ones and they didn't work good. This one works great and even detects irregular heart beats. I took this with me to my heart doctor and they checked it out it is accurate and my heart doctor was happy that I have a way to keep track of my blood pressure as it has a memory and saves it. This blood pressure monitor is not made cheap and it comes with batteries which I like because there is nothing more aggravating than getting a product and realizing that it needs batteries! So that was another plus another awesome feature on this bp monitor is that it has a 2 user setting so it saves your info for 2 different people. This is also easy to put your batteries in no need for a screw driver. I have had noth9ing but a good experience with this blood pressure monitor so if you need one this This blood pressure monitor uses advanced technology. This blood pressure monitor has a bright LCD screen with separate touch buttons. This blood pressure monitor is also easy to store and works on your upper arm. The BPM80A records up to 120 blood pressure readings 60 readings per user, with date and time memory recall. Graphical readings are classified in five different levels and color coded to represent the reading's level of hypertension. It also calculates and averages your blood pressure based on the last 3 readings and detects irregular heartbeats and any arrhythmias. Arm cuff fits upper arm circumference of 23-32 cm. The MeasuPro blood pressure monitor ships with 4 AAA batteries (included), medium to large sized arm cuff, carrying bag, and user manual. 2 year manufacturer's warranty included. Like I said I have tried several different bp monitors and none of them even come close to this one this is the best I have had.
