we used the snuza for a few months. works very well, as a breathing monitor. however, if baby is in one room and you are in another, you might not hear it go off. Also, at a few months old, we found that baby simply pulled the thing off his nappy! We now use an angelcare, and have to say it is fantastic, does exactly what we want it too, monitors breathing and allows us to hear easily when baby wakes up in another room. My wife and I have both attended a first aid course / cpr for babies, children, so are confident that ifm God forbid, it goes off, we can be of use.
