One other great feature is the recovery

Well, the distinguishing feature that made this Garmin appealing is the music capability

Garmin Fenix 5 with sapphire glassPROS - amazing features

So...useless music feature.

love all the work out features

Perfect Running watch with smart watch features!

I switched from a Samsung smart watch because I wanted a dedicated running watch with smart features, not a smart watch that could track runs.

Has so many helpful training features and you can download even more

The everyday features like step tracking and heart rate monitoring are also very useful

Still, the back light is good, and I like the "gesture" feature, where the backlight turns on when you raise and turn the watch.3.

Because the 645 does not work for outdoor swims, it does not have this feature

All the other reviews seem to be for the music version and those features are fairly prominent in complaints

I don't listen to music while running so that feature was unimportant to me, however I might have considered it if there was a reliable answer about whether or not you can listen to audiobooks via the music feature (sounds like you can if you don't mind stripping DRM, jumping hoops, and crossing fingers that it will actually work, in other words, don't bet on it)

I had big hopes for this one and was excited for the sharp look and additional features

I love the HR broadcast feature so that I can I sync my bike computer to it and see my heart rate on the computer.
