During the first year of your baby's life you'll be dependent on a nursery monitor to allow you to move freely about the house or catch a few zzz's yourself while your infant snoozes in his crib. The Crystal Clear Nursery Monitor lives up to its name, allowing you to listen without the annoying interference that can result with monitors that have too many channels. (Theirs has two.)
The monitor can be operated by battery or outlet (it comes with AC adapters), and has a listening range of 400 feet. For added convenience, the listening device comes with a belt clip.
