Review on Swann Garage Parking Assistant Sensor Alert Aid: Ultimate Car Stopper Indicator and Vehicle Park Assist Solution! by Chris Endricko

Complete and complete garbage. The light is on even when there is no movement or does not light up when there is movement. It flashes randomly for hours and then stops for no reason. I was driving the car tonight and it would never start, sometimes it turns red straight away or it just doesn't work; It's just completely incompatible with the way it works and that makes it completely unreliable. The design is actually really good because the light is attached to the cable so the sensor can be placed low and the light high, but that just doesn't work well enough. I trust him with my car. Buy a $50 tennis ball and hang it from the ceiling and save your money.
