It's a fitness tracker battle between the Fitbit Inspire HR and the Xiaomi Mi Band 4. One costs $100 and the other is $40, so which one is the best value?

These bands also have some smart features, like getting notifications from your phone, so let's break down what they can do and how they compare.
