Query: Terrible waste of money

This monitor worked for about 3 weeks and then was terrible. While plugged in, it will shut off for no reason and it took me about 1 week to figure out how to turn it back on, in the meantime, I was sleeping on the sofa so I could hear the baby at night. If I take a step outside it stops working. I hate this monitor and am getting a new one.
