I received my Fitbit Alta HR and immediately set it up. I have been using the Fitbit Flex and this was a definite step up. It was very easy to install if you just install the Fitbit app. It pretty much just walks you through the setup. I really like that this Fitbit gives you your heart rate. I also like that it has a reminder for you if you sit too long it will tell you "Let's take a stroll" or another reminder. I have to pay attention when I charge it as it was a little tricky lining up the charger with the holes on the back of the unit. Just make sure you see the battery charging on the face of the unit. If you tap it once it tells you the time and the date so it is a watch also and an alarm clock. If you tap it again you will next see the number of steps, third is your heart rate, then distance, calories burned and finally minutes active. This tracker also tracks your sleep. The best part is this tracker doesn't have to have a dongle to sync it as it is wireless. Another one of my favorite things is on your dashboard (that's what they call the site you go to for accumulation of steps, resting hear rate, etc) , you can engage in competitions with other users. This really gets me going as I like a friendly competition. Overall, I would highly recommend the Fitbit Alta HR to help you keep fit.
