i had a leap frog digital advanced one, which was quite perfect for my little one,The monitor was really easy to set up and you can hear and 'see' any sounds in the baby's room very clearly using the parent unit and its noise indication lights. You can even turn the sound down on the parent unit and just use the lights to monitor the room. The lullabies are very clear, not jangly at all, and you can set to 'Play all' for some gentle background music and even select/turn these on or off from the Parent unit if you want to. The display is very clear on both the baby and the parent monitor with big digital digits,to show you the temperature and a backlight so that you don't have to turn the light on to see it. I've also used the torch on the parent unit and like the travel bag to keep everything together for when we go away.
