From such a well thought-out effect that the pacifier is lit, I had never heard before. At first I thought that I have to day always "charge" the pacifier in the light, but that's not the case. The pacifier is lit all night. Of course, the brightness can with the hours for some, but can also be found in the advanced night nor the lost pacifier. It's really a good idea, because then one does not have to turn on the light to find the pacifier, or even forever rumtasten in the dark, but with a handle he's back in the mouth. The pacifier also does not light up so much as it disturbs the baby to sleep. All in all really great - even for the price.
