Countless times I have woken up with my watch's battery completely flat. This is a 450€ watch (FR645M) and we all know that draining a battery to 0% is very detrimental to it. Now, I am not the one choosing to end up in this situation due to negligence and not charging the watch when needed: instead, Garmin has been time and again unable to provide software that behaves properly. In other words, if my 450€ watch deteriorates too fast, it is Garmin's fault, not mine.
Garmin, do get your act together, do fix your watches, and do make commercial gestures for those affected by bugs that should only be found in beta-version products.
