    I bought this thinking it was going to be so easy to use and help me feel safe living by myself. I was never able to get everything matched up, it would randomly go off and even after I unplugged everything, one night, the base controller started beeping so loud it scared me to death. I couldn't it to stop as everything had been unplugged so I had to take it apart and take the batteries out. I would not recommend this product to anyone!
