Sony Babycall Nursery Monitor is the best monitor out there- hands down. We bought 3 other monitors for our baby and all either produced too much static, or did not have the range we wanted. We came across the Sony Babycall and it was crystal clear and far reaching. We have a big yard, so often at nap time we like to work in the garden- having a reliable monitor is very important to us. I also like that the monitor is rechargeable and has different channels to choose from. When we had our second child, we again purchased a Sony BabyCall Monitor. We now use both of them and have no problems whatsoever....
