Amazing and useful.
Amazing technology. It takes a while to figure out and use all the data this device gathers. I definitely recommend it. A real value when compared to alternatives as well.
Just What I Wanted!
I previously had a Garmin vivoactive and it worked great to meet my needs, but once it broke I decided to look into other Garmin wearables rather than just replace my vivoactive. I am glad I found this option! It is simple to use, and is exactly what I needed for the activities that I wanted to track. I like that you can customize it and add widgets. I don't plan to do a lot with that, but it's nice having the option.
