Review on Renewed Garmin VivoFit 4 Activity Tracker with Color Display - Small/Medium: Enhanced Fitness Monitoring by Danny Poulin

This is an older version than the previous version. Basically the same, this one is actually a lot bigger but you can't tell when you have a group. I found it to be a lot less accurate than my old one which I sadly gave away, especially when I get to altitude and after about 25 minutes of exercise it finally realizes I'm exercising and starts tracking progress and then shuts off. a few minutes after the workout is still going (I'm not slow and can keep a steady pace so I don't get it at all). It keeps time pretty well, you have to sync it from time to time to set the clock (perhaps once every few months), and the battery seems to last a year. It works well as a watch, but I wouldn't buy the Vivofit 4 again.
