It adapts to all kinds of bottles, even those with wide necks (Philips Avent, for example).
Its big plus is also to propose the use in the car. The ability to heat small pots, when we go on weekend or for the day, is very convenient.
However, we often use the information to find out the amount of water to be paid depending on the material of the bottle (glass / polypropylene), the liquid temperature (20 ° / 4 °), wide neck / normal and quantity heat (120 to 330 ml) ... And ditto for small pots. All these figures are a little scared at first, but after a few uses, times are better mastery and the amount of water to pour.
The heating times vary from 1 minute 33 (120 ml bottle, narrow mouth, glass with milk at room temperature) for about 21 minutes for a 330 ml bottle made of polypropylene that comes out of the fridge. In other words, you have to book well in advance to avoid being picked guard. Especially as these approximate heating time are considerably underestimated.
After, it is not out the clock to each bottle as the bottle warmer will stop automatically as soon as all the water has evaporated.
According to the instructions in the manual, do not use the bottle warmer while the car is moving ... it's easy to say! But I do not see myself running the engine on site 30 minutes to heat a bottle! So, when I am not led, I hold my feet on the ground between the time it heats.
