My wife and I purchased a BT baby monitor + plus

The Baby Monitor PLUS includes an LCD screen, 5 lullabies (can be changed by parent unit or baby unit), nightlight and a temperature monitor (with high & low alarms)- not to mention a range of up to 300 metres and an Intercom feature means that a constant link is maintained between parent and baby.

Portable parent unit (on rechargeable base) and back-up batteries in baby unit!

A must have item for the nursery.... highly recommended.... I wouldnt buy any other model!
