We bought this very affordable baby monitor, because we thought a simple baby monitor does. It does not have the send and receive. The parts, however, have proven to be true battery eater. The imaging range is true, but the quality of reception is unfortunately not good. You can hear both channels (which for this are there to handle noise) more noise than the baby. Only when it really screams, you can hear it in the baby monitor. Otherwise you can hear only noise and you do not know it has now just turned upside down or it is wake up. We will now establish a higher quality device. This baby monitor unfortunately it saves on the wrong place!
