How do people like their 5?

I have a gen 3 which has been great, but the battery life is starting to go. Since it's been about 3 years at this point, I'm wondering if I should update with the 5 an stick with what I'm used to-- or look into other wearables, which have also matured in that time.

I see a lot of complaints here, but assume no one's making a post about their product working just fine.

Appreciate your thoughts!
