I bought several of these for myself and my family. I wear mine on the waistband or the waistband of my shorts from morning to night. It is small and does not interfere with carrying. Your battery lasted just over a year, so that's good. Features a seven-day step log that you can scroll through to see your week's effort. To be honest I don't care about the calorie function as I'm working on increasing my steps. A. It has an accurate clock function. I don't wear a watch anymore, I just take it off and look. A bit like in the days of pocket watches. A. I had another brand that had a bear to open access to the battery. It is much easier.
