I am not disappointed with my purchase because it is as I wanted. More need batteries to operate, His office works on a period of at least 3 days counting nap morning and the afternoon. It indicates the temperature of the room, which is a little more especially during the summer. It has a rocking function, and you can also talk to the baby (I do not function but can be used for other, unwanted mom) The only downside of this baby monitor is that when the baby cries, a light comes on but but does not show the intensity of crying. Indeed, this would go only when baby crying is intense and not by whim
