Title: Hmm.. Are there FDA regulations for these?
Review: I ordered two of them one for me and the other for my parents. They arrived fine and there was no issues with amazon's amazing supply chain management. I wanted to calibrate them together. One was showing a reading of 90/60 and the other one show 105/65 taken within an interval of 5 minutes. I am a normal healthy male with 120/80. The ones in walmart / publix / target / my doctors office show the correct 120/80. But this one has such a different reading. I tried them at least 20 times and the closest that I got was 110/68. In my opinion this is still way too much of deviation and returned both of them. I don't understand how such a deviation is acceptable for a life saving medical device.
