"[This review was collected as part of a promotion.] Once I had download the heart app on my phone, it was easy to store the readings. No need to write them down for reference. The cuff came in two different sizes, which is great for families who have both small and larger arms. The machine was easy to use, and seemed accurate in the readings. The only negative I could really find, was a couple of times the cuff just kept getting tighter and tighter without any readings. It would only stop if I turned the machine off. Causing bruising to my arm, I am sure that would turn an old person off the machine, as their skin tends to bruise far more easily. A stop button would have stopped the bruising."
