Query: GREAT ALARM

I have owned other alarm systems in the past and NONE were as easy to install as this alarm! Easy to follow instructions make it a snap! Only one wire and ground the alarm and you have the best alarm on the market. Its hard to believe that this alarm is so cheap! I had another type of alarm and it cost twice as much and did not do half as much as this alarm! I liked it so much I have now bought two others for family members!
