If this is anything like the FP Lights and Sounds monitor then I can vouch for it as they are great.
Can't see it cheaper anywhere else - £29.99 @ Amazon
The new Fisher Price Precious Planet Sounds 'N Lights Monitor includes two cute characters - a polar bear and a penguin - sitting on an iceberg with a clear panel behind them that reflects glowing lights.
The lights on the receiver are now on both sides, allowing greater visibility around the house. This monitor also includes soothing lights that glow on and off on the transmitter to calm baby and provide a night light for the nursery. It also features a low battery indicator on the receiver.
The monitor has five traditional LED lights to see baby's call, volume control, AC/DC power featuring an energy saving power cord, plus a power light.
Suitable for children aged from birth.
