If you find that 4/5 min is a bit long to prepare a cup of coffee and if you start to grow impatient,here is the solution to save some time:
preheat your machine!
If you know that you will stop to have your coffee break, fill the reservoir with cold water before leaving, close the lid (without putting a pod) and when you are about to stop, just press the power button to heat the water.
When you are ready to drink your coffee, you have just to restart your Handcoffee (by pressing the power button) and put the pod! That's it !
