The only times I don't wear it are sleeping (it does have a wrist attachment but I don't find it very useful), when wet (bath/shower/swimming) and during ballet classes (because there's nowhere on my ballet gear to put it!).
I love all the graphs.
I love reaching my daily goals, which are currently set at:
16 flights of stairs (newly increased from 14)
30 "active minutes"
But most importantly, it has helped me become more active and healthier than I was last summer. During the day at work I am more likely to be I my feet; I choose to walk down the corridor or up and down stairs to run errands more often; and I plan my day to include small chunks of walking where possible. I really love it!
