Whats you thoughts on them? I have a meeting with ADT in a couple hours. I got a notice from USAA saying they offer system discounts along with a nice discount on home owners insurance. Me and the wife are gone more than we are home so we talked about it and thought it would be nice to give a more secure feeling. But then we look at people like our parents how have lived in their homes for 30+ years and never seen the need for one. And then my grandma, been in the same house her WHOLE life, born raise and it was pasted onto her, she have never had one either..
