Query: Doesn't last long

This monitor worked really well for about six months. I could hear my daughter breathing, I could hear traffic go by outside her window, and I could hear the echo of my husband and I laughing from our living room! It was great because it made me feel really safe - but after about siz months, I was unable to unplug it. If I wanted to take it to another room with me, as soon as I would unplug it, it would stop working. if you slammed it with the palm of your hand, the sound would come in and out... Now it doesn't even do that. If I dont' have this thing plugged it, it does not work. So, I am not able to leave the room that I am plugged into. Which pretty much defeats the whole purpose of having a baby monitor with such a wide range and rechargeable batteries. This thing is pretty much worthless to me now. I'm shopping around for a new one that will allow me to actually walk around my house. I'm very disappointed because I can't get my money back on this junk.
