For best accuracy and ease of use, buy one with a cuff for the upper arm that automatically inflates and automatically records the pressure. The American Heart Association doesn't recommend wrist or finger home blood pressure monitors.

The American Heart Association recommends referencing The British Hypertension Society for validated monitors when choosing a model.

The best method of choosing the right monitor is to ask your pharmacist or your primary care physician.
