Great product, must buy

Ease of mind!

These alarms are awesome! I had my catalytic converter stolen right in our driveway about a year ago. It took the thieves less than 2 minutes to steal it! I then found these alarms online and we now have them on all 3 cars/trucks in our family. They are very sensitive and will go off when the exhaust area gets disturbed, and it gives us tremendous peace of mind now. We know if they try to steal the converter again they will have a loud surprise!

Stealth Alarm

Its awesome. A little added security besides the car alarm from the manufacturer, a Cat Shield and the Club. All I'm missing is The Ring:)
