Fitness trackers with a rubber body

Rubber housing

— for several reasons, rubber is found predominantly among fitness trackers and beacons for children (see "Type"). This material is strong enough, reliable, resistant to water, does not oxidize and almost does not wear out; and one of its distinguishing features is softness. These properties are especially important for children's and sports gadgets. In addition, rubber is inexpensive, and its colour can be almost any. Note that the back cover of such a case can be made of metal — this simplifies the use of various sensors.
