Title: Yipes!!
Review: I installed the first half of my new security system over the weekend and my goodness does it work! I've accidentally set it off twice so far. You get a lot of noise out of three AAA batteries. Installation on metal doors is problematic--the stickyback tape doesn't want to hold--and the screw in the battery door can't stand up to a screwdriver, but aside from that all is well. Thanks.
