Query: horrible

I received this monitor set as a gift. One of the receivers didn't even work straight from the package. When I called customer support, they were so uncooperative and told me that since I didn't have the receipt, there were nothing they can do. That was the least of the problems we experienced with this monitor. The static it picks up is unbelievable! It would pick up the noise of our dryer so loudly that we always questions whether we hear the baby. Also, the whole set stopped working one night after a few weeks, so now we have to look for a new monitor set pronto!
