I wear this Fitbit watch every night and day, and I love it for tracking my calories burned and seeing my daily movement.
Two things I dislike about this watch are that you have to wear it consecutively for seven days before it will log and show your sleep cycle, which I sometimes forget to do when it's charging or after showering.
Another thing is that it counts steps even when I'm just moving my hands while cooking, resulting in inaccurate readings and inflated step counts.
I do like how you can change the bands; I've already switched to a scrunchie fabric band.
