Bests & Worsts Reviews from Amazon

I am a clinical pharmacist and I bought this primarily to show my patients how to check their blood pressure (BP) at home. I have seen quite a few BP machines my patients use and I usually check the machine readings against my own which is done manually. The HEM-712C is one that is inexpensive but gives accurate readings. Do keep in mind that the literature suggests that most machines made after 2000 should be accurate and technique matters more: 1) Know how to use your machine. Read the manual. 2) Sit down for a least 5 minutes before checking your BP 3) Do not talk while checking BP. The sensor can pick up the vibration 4) When you are have a full stomach, or need to go to the restroom, readings are not accurate 5) Do not wear tight clothing or cross your legs when checking BP (Note: wrist and finger BP machine are generally not as accurate) Addendum (5/13/2012): There are many iterations of the HEM-712C, with some re-branded by other companies. They all generally has the same good accuracy, whether they are older or newer models, from my experience validating them for my patients. The newer models that appears in the past couple of years appear to be just as accurate. There is no need to get the more expensive models, which only offer more functions. Some more expensive models offer two cuff sizes, large and regular, which may be useful for household with different arm sizes.
