Garmin Fenix 3 HR

Pros and Cons

Pros

• Metal case and glass cover
• Wi-Fi for syncing directly, without battery draining bluetooth enabled on phone and watch
• Map display of waypoints and current track works like a charm
• Highly customization of display features

Cons

• Optical HR measurement does not work for me when sweating (HR=199 bpm at low pace is at least 40 bpm wrong, so no minor inaccuracy)
• Sleep diagnostics does not use HR data
• Sleep is only detected once per day, so no afternoon nap possible in the data model
• No build in way to manage and transport waypoints in Garmin Connect (two 3rd party apps help to fill the gap, see below)
• PC tool "BaseCamp" and USB cable required for editing tracks and waypoints
• PC tool "Garmin Express" and USB cable required for setting Wi-Fi Password
• 3rd party watch faces are very slow (several seconds delay when browsing through display pages)

Low hanging fruits for Garmin Connect app

• Sleep diagnostics using HR data and allowing for more than one sleep / nap per day
• Enable Garmin Connect to manage and transport waypoints to phone
• Enable Garmin Connect to set Wi-Fi passwords
