A handy blood pressure and very easy to use. It works with 2 batteries that are provided. The settings are very quick and easy to do and the unit can be used immediately. MIT 5 Precision allows you to store up to 90 memories for convenient monitor your measurements and have them analyzed by your doctor. It measures the heart rate, systolic blood pressure (which corresponds to the arterial pressure measured during the systole phase, that is to say during the contraction of the heart) and diastolic pressure (which corresponds to the arterial pressure measured during the systole phase, that is to say during the contraction of the heart) In short I recommend it.
