I read all of the reviews about the battery popping out and loosing it, as well as the inconveniences of battery removal for charging it.

The battery was difficult to change

Now the battery is dead

I decided to put a new battery in it even though I couldn't believe the battery was already dead

What I like: good battery life, very comfortable wrist band

Within the first 3 weeks the battery died yet the app always indicated the battery as full.
