re: What is your blood pressure?

Do any of you monitor your BP on a daily basis? If so, what monitor do you use? I had one from Wal Greens and then got another one from the apple store. However, one, or maybe both, aren't accurate as I have taken multiple readings of a 2 week period, using one monitor followed by an immediate follow up reading using the other monitor and all the readings are usually off by 10 on the systolic reading.
