The Vivosmart HR+ refurbished is the upgrade that I sought for my Vivofit 1. The HR+ arrived in a genuine Garmin Refurbished box and included the watch, charger, manual, and 1-year warranty. Garmin Express recognized my new watch. I kept my Vivofit 1 to wear when the HR+ is charging. Garmin TrueUp can tell whether my activity is from the VS HR+, VF 1, or an illegal duplicate from both. There are several great features: (1) GPS will produce a nice map of my outdoor activities, (2) Unlike the VF 1, I can now get Garmin credit for most activities (steps, runs, rides, swims, miles, cardio, current HR, resting HR, gym equipment, Intensity Minutes, weather, outdoor elevation), (3) Every feature of Garmin Connect works except features needing to know my VO2Max, exercise efficiency, or indoor virtual hills. The cons are minor but I'll list them: (1) While most outdoor maps are good, a few have weird gaps when the GPS satellite link is momentarily lost (my solution is to save the good maps as "courses"), (2) GPS drains the batteries, requiring a recharge every 2 days, but I have two watches so I wear the VF 1 while the VS HR+ charges, (3) the VS HR+ will not award credit for hill work on recumbent bikes, improvement in my VO2Max, or maximum exercise efficiency (there is no solution except a more expensive watch if you ride indoor bikes, care if your VO2Max is ~50, or you are approaching Level 4 exercise efficiency).
