Title: Defective ... Junk ... Buyer beware.
Review: After I received this product, I installed three C size battery in the receiver. The light is on for a few seconds, and then it goes off. The sensor unit seems to work. I thought the receiver's batterys are bad. So I went out to buy the new battery. After I install the new battery again, the receiver is still unresponsive. It is frustrating. It is a waste of time and money. I think the seller knows this product is an unreliable piece of junk, so they sell it cheap. So, people won't even bother to return it. Buyer beware!
