I'm not good at reading pictures, especially small ones. The written instructions were confusing and seemed incomplete - the on-screen images in the instructions should help. When the tracker finally connected to the phone, there seemed to be a lag in the information every time the app was used. Some information between the app and the tracker does not match. The blood pressure differs greatly from all other readings taken at the same time and the test adjustment did not work. The pedometer on the tracker doesn't match what the app shows. I've asked others who have similar trackers and they haven't had these issues. I need to push one final source before posting back. The tracker is easy to read and easy to use. The bracelet even fits my small hand. One of the reasons I chose it was that it is suitable for men, women and children. The tracker was sold out when I ordered it, but I received it a week before shipping.
