Negative Positive
Title: Save your money...
Review: I have been trying for almost two years to get this thing to work right. I have adjusted and re-positioned until I am blue in the face. It works with some vehicles in some weather conditions, but calling it "undependable" is being kind. I have replaced it with a Might Mule system that works by electro magnetic sensor that is buried next to the driveway and it is a 100% improvement that works "every time" a car goes by on the driveway.
Is the review positive or negative?
