It's small, easy to use, and the battery holds for a great amount of time. I also like how this is a thinner model because you're able to use bracelets on the same arm as the watch.

Purchased this Fitbit online for my wife from Harvey Norman about a month ago. She loves it, all the features you could ask for. Lasts for approx a week between charges and looks good too.
