Query: Terrible monitor-Static, Static, Static!!!

We received this monitor for free and I can honestly say you get what you pay for. Don't waste your money on this monitor. It worked well for a couple of months but then all we got was static. We couldn't hear the baby over the static. Everything interferes with this monitor-phones, tv's, radios,- even when they are turned off!! In addition, we had to replace the 9 volt battery in the monitor every other day unless we had it plugged into the wall adaptor. We spent more on the batteries than what the monitor was worth! Tomorrow we are going to buy a new monitor!
