Overview
This is a Fitbit-branded fitness tracker in a black case with a Midnight Zen band. Beyond the brand and color, the listing does not provide screen size, sensor list or battery life, so shoppers should confirm those details on the product page before buying.
The listing identifies this only by its Amazon catalog number rather than a named Fitbit model such as Charge or Inspire, and the color is given as Black/Midnight Zen. Fitbit trackers in this price and rating range typically track steps, heart rate and sleep, but none of those functions are confirmed in the data provided here.
