This monitor comes with one base that lights up for 15 minutes and two receivers with clips. The receivers can be battery operated or plugged-in to the wall.
We chose this monitor because it comes with the two receivers and the base lights up. We also liked how it has a noise level indicator on the monitor so we could see if our son was crying or making a lot of noise. At first this was a great monitor and we kept a receiver in our basement and main level of the house. We didn't need the nightlight too much when our son was an infant. The clarity of the sound was great and we could even hear our son breathing well he slept.
We've now had the monitor for 2 years and are not happy with the sound quality/reception of the receivers. There is often static and lots of interference on the channel. In fact, one receiver is no longer operational because the static is so severe. The nightlight is very useful to us now, though. Our son likes to fall asleep with the light on.
