I find the battery doesn't last very long. I'm lucky to get a day and a half to, two days. Only allows eight alarms, I work shift work, so I have different alarms for the different shift. Every two weeks I have to delete some to add the others. Band is always stinky and I wipe it down every day with A Lysol wipe. Says I'm sleeping when I'm just sitting down. Doesn't count my steps if I have something in my hands, which I often do at work. Often doesn't count my steps since they are shorter than most. Don't like that it isn't water proof.
