My doctor had my purchase this to check my blood pressure daily and keep track for a few months. This one syncs to my iphone using the Omron health app which is perfect so everything is logged in my account. I don't have to sit and write or keep a notebook with numbers. I purchased the monitor that included the wall plug so that I don't have to deal with batteries dying out when I need to use it. At first I was so annoyed that I had to take the time to take my blood pressure every day but quickly noticed, this monitor does it so quickly that its not even a big deal. The arm cuff is a universal size, the monitor is small and its not noisy nor does it hurt. I totally recommend. My doctor mentioned that the reading with this monitor are very accurate in comparison to other brands.
