Excellent 2-way communication system like a normal baby monitor but with more. For starters you don't have to have the sound on all the time and instead you can have some sound level indicator LEDS which light up as the volume increases. This saves battery. The second top feature is obviously the sensor mat which detects movement and breathing and will alert you if it stops for too long. There is an optional clicking sound on the receiver for each movement, but an LED will flash on the receiver for each movement. The transmitter which sits in the cot also doubles as an orange night light with 3 settings and this can be controlled remotely from the receiver, which will also tell you what setting the night light is on via the LCD screen. The LED screen on both units shows the temperature of the cot and various settings and will light up if something happens or you use the receiver's buttons. I think the sensitivity of the pad can be changed but I'm not 100% sure about that. You can walk around with the 'parent unit' or receiver or have it docked in it's charging station. You can also talk back to the baby unit using a button on the side of the parent unit. The only downer on this unit is you have to keep remembering to switch off the sensor pad at the baby unit when you take the baby out, or the alarm will sound. While this doesn't sounds too bad, you have to remember it in the middle of the night every 2 hours when feeding. Only paid £50 and it's a bargain for that price.
