I bought the vivofit jr for my 3 year old (mainly to satisfy my curiosity about how much he moves per day, but it was also useful for storing coins in the app for a potty training reward) and I appreciate the other reviews saying it's the smallest potty train you can find on Amazon. He is a slim 3 year old and although the small size is still loose it is still small enough to put on or take off over your hand, however you will need to stretch it considerably. The quality seems excellent so far. He is very active and rude and did not harm him.
