I found that this limits the utility of the device in colder weather where it's necessary to keep batteries close to the body and warm so as to not quickly drain due to the cold.

, it has good battery life and the app is very user friendly.

The battery, sadly, is non replaceable.

The app's offline map was great for navigating town as well as for creating pins and sharing them when any of us wanted to mark a point of interest

I've used mine throughout trips to SE Asia, the Australian outback, New Zealand, as well as during hiking trips in the US
