Unfortunately they are not good “allowed “ in water or the shower so it’s challenging to be active and then having to always be aware to take off the watch.
I referee soccer & rugby many times in the rain and now can’t wear my fitness tracker in those activities, and unsure if it will hold up when my many hiking excursions in the BC mountains many times in rainy weather.
If I need to always be focused to dry off my watch after every activity (wet weather or heavy sweating) it is a concern.
