Title: Didn't work for me
Review: Unfortunately, this is my first negative review out of too many good ones to count. Maybe I didn't read carefully enough before making the purchase but in order fo this to work you need to have the right door. I will describe as best as possible, but basically the door and the entry to need to align perfectly to give the two pieces that make up this product a chance to meet and sound off. Second, when I sounded the on switch the device just kept ringing regardless if the second piece was beside the main unit or not. I am not afraid to say this might be my human error, but with that said the device was advertised to be a lot simplier than what I experienced and I am the most electonic/tech savvy person I know so this item had to go back:(
