5x sapphire here, about 4 years. I use it as a backup on hunts and typically will set a waypoint at the truck, or camp sit or wherever we start. It does a decent job of making a breadcrumb trail, but wouldn't want to use as my primary navigation unit. I use it for workouts and mostly for mountain biking, hiking and running. My only real complaint is the charging port. You have to make sure it is uber clean and even at that the cable doesn't fit up well. Just have to play with it a bit to get it to connect. My battery life isn't as good as it used to be but I still get 7 days or so between charges, depending on workout activity, but as stated it is 4 years old.
