This arm blood pressure monitor is absolutely fantastic. It is by far the best home device I have used. I ordered the large arm cuff and it fit both my arm and my wife's arm (who generally uses a small band). The cuff is extremely accurate and matched my readings I had just had at the doctor's office the day before. I love the extra large display as it is easy to read and it fits comfortably back into the packaging for storage. It's extremely easy to set up and get working, but it does come with instructions if you want to double check your setup. GET HERE ON AMAZON
