Query: A disappointing product

We registered for this monitor and received it at the baby shower. Upon our first opportunity to use it (and already throwing the box away)we experienced nothing but sleep-shattering feedback and the privilege of eavesdropping on our neighbors' phone conversations. Unfortunately, the function of monitoriing our child in his nursery was unavailable through the use of this product. We will try to return this product as quickly as we can.
