Grobag egg, room thermometer.

Grobag egg, it’s a room thermometer that indicates the current temperature via an LCD display and by shining a specific color. No other thermometer in the world gives parents such a simple colour warning system, coupled with a fully visible digital readout of their children's room temperature. The Easter time is coming and what a nice present for the new parents.
