Negative Positive
Title: No on/off button.
Review: We have unfortunately left this warmer on on several occasions. There is no on/off switch, therefore the unit has to be unplugged to turn it off. When left on, eventually the water evaporates and is left empty and HOT. It seems there are cheaper units that do the same thing with on/off switches and even auto shut off options like the "Quick Serve" by The First Years. We will be buying that one and throwing the Avent one out.
Is the review positive or negative?
