I read all the reviews before purchasing and loved the features. I really set out to find a watch that communicates with my phone and counts steps so I don't have to carry my phone with me all the time. Well, the step counting feature is very inaccurate and partially integrates with other features in my iPhone, but not in terms of steps. The heart rate function is accurate, but the blood pressure function is not. The battery should last between 7 and 21 days. I had to charge it after 52 hours. For now. I assume I have a digital watch that counts my heart rate and has a nice picture of my granddaughter as the background screen. I am extremely disappointed.
