Title: Doesn't work
Review: I purchased this with the hopes of knowing when someone drove in my driveway. Now I know every time the wind blows because tree limbs blowing in the wind set it off. I never realized how windy it is outside. I found the magnetic driveway alarms are the way to go. Save your money and buy a good magnetic alarm. Do your research before wasting your money.
