How it works:

Step 1

Boil fresh tap water and measure out 210 mL with the break-proof cup

Step 2

Turn the cooling element 180°, put it on the threaded neck of the cup and screw them together so nothing drips

Step 3

Turn the screwed unit 180° again and put it directly over the neck of the baby bottle. Hot water runs automatically through the cooling coil which is surrounded by the cooling water and cools down the boiling water
