Coffee mug with inbuilt plunger

A gift I got today - it's a sturdy little plastic coffee mug with an inbuilt coffee plunger. You pull out the plunger using the tab on the side (it's raised in this shot), put the coffee in, add water, stir, the plunge it, add milk and sugar and that's it!

 

This could make the difference between me not bothering to make my own coffee at work.
