We have the previous 'orange' model of this monitor (before Avent paired up with Philips to make this model), and it has been absolutely fantastic for our 1st child. So we bought this new 'blue' Avent/Philips model for our 2nd child, thinking it would be identical. However, rather than provide a continuous link to the baby's room, it only kicks in when a sound is made. This means that you can miss the first part of the noise. Hardly reassuring. In fact, we have heard our child cough from the room below, and the monitor has not picked it up, and has only kicked in AFTER the cough. We took the monitor back, thinking it was faulty, and had a replacement, but the 2nd one is doing exactly the same. I presume that this is an energy saving feature, but I will be taking it back and buying a different make. Such a shame as the first generation of this monitor is absolutely faultless.
