It's DAY ONE with the Garmin Vivofit 4. My initial impressions are good. Fitbit Alta never would sync with my phone, so I am super happy that I had no trouble with setup or repeated syncing and I am hopeful that continues. I very much appreciate the watch-style band, which is secure and not likely to fall off my wrist (as the Alta did), and the fact that I will not be charging it regularly, as it has a replaceable battery that is good for a year. It is also low profile and light weight. While not exactly ""pretty"", it sticks out way less than my Alta did and feels lighter and I think I am going to like that as well. The app is quite navigable. My needs are very basic and I actually turned off some of the display options. There are color customizations. I just want a little motivation and a way to track some weekly walking - Date, Time, Steps, Distance walked, and duration of time spent exercising. It will do many other things, including help find your phone, which I very well may need in the future, LOL. Negatives? The display is readable, just smaller and dimmer than I am used to. I'm anti-sound, so if this thing starts chirping at me, I am going to have to go back in and turn some more things off! However, I have zero qualms at this point for giving up my non-syncing Alta and am not likely to go back to finicky Fitbit devices. Someone needing LOTS of features and finesse most likely should upgrade; however, if your needs are pretty basic, this will do nicely.
