This monitor worked well for the first week after our son was born but then began to only provide us with static noise or a loud whine instead of providing us the security we had thought we'd be getting. We played with the channels and even moved the receiver to a different location within the nursery but nothing has worked. All we basically have is a $30 night light. Very dissapointing.
