Query: works fine

i had shopped for a blood pressure monitor for a few months at local retail stores, before thinking Amazon would carry such a product! I should have known better since I am an avid Amazon shopper! The product works fine. It seems pretty accurate, too. the arm band is a bit large in width for my arm, but I havent noticed this to affect the numbers too much.
