This is a very clever easy device to simply check on the room temperature.

The egg changes colour according to the warmth of the room so that you are

instantly aware if the room has become too cold or even too hot.

I have shown it in the photos in both a warm and cool room 

to show that it is working!

It has not been used as this was a duplicate present so we just tested it out

before listing for sale.

Comes boxed complete with plug and instruction manual.
