Title: USELESS to the nth degree. . .
Review: Purchased this item, installed it per instructions and began testing. The chime unit was originally approximately 8' from the sensor unit and would NOT sound an alarm. I kept moving the chime unit closer to the sensor unit in order to find a suitable place to hang the chime unit permanently. Finaly, at approximately 12", the chime unit was able to pick up the signal from the sensor unit. A complete waste of time and money. Too bad I had to give it even ONE star.
