Query: Not as good as I hoped

We bought this at the suggestion of a friend, and we liked it from the beginning. It is very easy to use, and it picked up every sound from the nursery. After a few days of use, this proved to be more of a bad thing than good. Every time our baby even rolls over in the crib, we can hear the rustling of the sheets. And even at the lowest volume setting, the bright lights flash and wake us up.After 8 months, both parent units are crackling with interference on a constant basis. And they both lose their signal from the transmitter and start beeping incessantly even when they are only one room away.We are looking to buy a new monitor now. This one is now unacceptable.
