At first I was just looking for a pedometer but found one with additional features. I have actually bought several of these for family members. Mine seems to work very well. I can't view messages or get call notifications, but that's not what I was looking for anyway. I didn't want to have to carry my cell phone with me all the time as a pedometer. I found the sleep monitor amazing as I know I've never slept well, but now I can actually see how many hours of deep sleep I actually get. As for heart rate. I'm not sure how accurate that is, but the blood pressure reading is definitely wrong, but then again, I have a blood pressure cuff and monitor on my wrist, so I wasn't looking for that feature. If you're looking for a cheap tracker and not a lot of features, this is a great deal.
