I'm quite happy with my Coros upgrade. It's really shown me that Apple Watches are a general catch all with feature bloat that don't do anything super well for serious activity seekers, yet its main requirement is the user be tethered to a charger every damn day - sometimes multiple times. That being said though, once this Coros kicks the bucket, I will being giving a lot of thought into whether I will be purchasing another activity tracker. Even with this new device that lasts 2~ weeks on a charge, I find myself missing the simplicity of my Casio G-Shock - a device that simply works. My phone still functions as a great activity tracker for biking, running and brief hikes, but lacks the real battery life needed for backpacking - which is my only holdout.
