Title: Less than one star
Review: Absolute waste of time and money. I installed this on the front of my garage to catch anyone coming up the drive. My daughter backed out of the driveway in a 3500# car and it never went off. False alarms every couple of hours. It woke me up twice the first night before I turned it off. WARNING ON THIS PRODUCT - DO NOT BUY. It's coming back Amazon.
