Query: Huge Disappointment

This product is lame. Half the time I receive the flat line bars and the remote unit is 5 feet away separated by a single pane of glass. I have the pix to prove it. Tech support was worthless and told me they did not have a replacement to send me! They said contact Amazon! Shame on Amazon for carrying products from Oregon Scientific. My next stop is the Better Business Bureau.
