    Too many false alarms =(Review by Anonymous
    I hate giving bad reviews but this thing just cost me $250 in police fines. In a year and a half this has gone off 4 times falsely at our store. Once from pressure washing (which I can understand if it hit the glass) and 3 other times from fire trucks or ambulances going by. We got 3 warning and every instance past this the police dept. charges $250. So now we simply are going to go without it. (Posted on 3/27/2015)
