So far I really like this product. It has allowed me to monitor my baby when I put him down for a nap.
The couple things that I note which are a touch inconvenient: Relies on the phone app, my phone is in a 'do not disturb' mode of a night as to prevent disruption from unexpected calls, messages, and other apps on my phone alerting. For this reason I have also purchased an audio only monitor so I can hear when my baby wakes. It would be nice if this device also had an separate audio transmitter so that it could be left on overnight (I am not aware of an option to allow just this app to sound when my phone is in DND mode). It would also be nice if I could feed my music into the playlists on the app (so far I have not identified a way to do this). There is however a good selection of music, sounds, stories on the device anyway.
