Love this product. I'm not fitness-mad, but I really like to see my bpm during the day, exercising, at rest. I like to reach my steps goal, and like the reminders to get up and walk. 'They' reckon that 'sitting is the new smoking', so it's great to get reminders that I've been sitting still for an hour, just to get up and stretch my legs. I love the non-fitness feature of being able to see who is calling / messaging me on my mobile without having to check my phone. Messages scroll across my fitbit. Was great to get sleep patterns as well... must improve ! I wear it constantly every day, no issues at all with it, glad I bought it.
