Review on Refurbished Garmin 101-N1995-03 Large vivosmart 4 Smart Fitness Tracker - Black/Slate by Dana Mahendra

Accuracy and battery life are excellent. Looks like new, works as it should. I really love everything he can do, even if I haven't learned everything yet. More importantly, it's easy to use and you don't need an app to keep using it (but you do need one to set it up). It's petite, fits my small wrist well, but my husband has one too, even with a large wrist. I will say that a man probably needs xlarge even though he has a large and barely fits.
