It's too bad that the icloud site does not work. I had severe headaches and could not consult a doctor, and therefore I decided to buy a Lifesource blood pressure monitor. I read the instructions and after some training with the cuff was able to get a good reading. I am confident the readings are accurate and I am very pleased with my purchase, check this site out. When measuring blood pressure, be sure to keep your hand at heart level, keep yourself level on the floor and do not move.
