THE "HIJACK BUSTER"® auto anti hijack and theft deterrent system COMPARATIVES The other electronic companies that produce anti carjacking devices are Clifford Electronics "Blackjack", Secure Products "Avenger", Accell Electronics "Stopjack", Jacobs Electronics "Stopaction", "Safe T Man" Bullet resistant glass. Clifford Electronics boasts the best and offers a code entry device that needs to be activated before the auto can be moved. In other words, the carjacker needs to punch a code in before they can get the auto to drive. We believe that this is highly dangerons and risky because of the reality and possibility of of kidnap, carjack, and murder if you do not punch in the code as the carjacker demands. The "Avenger" by Secure Products operates when a door is opened and the engine is running. After a time delay the auto becomes disabled and then an announcement informs the carjacker of an eminent 50,000 volt electric shock. This system can also be foiled by a carjacker who orders you to stop the engine and then gets in and drives away. We also believe the ethics and legality of delivering electric shocks may be found illegal and dangerous. The Safe T Man manequins according to ourselves and police authorities are not going to stop a man with a gun who wants your auto. At close range you can recognize that.the manequins are not real people. Bullet proof glass also offers slight resistance since the carjacker may point the gun at you through the roof or door of the auto. Obviously this is insufficient to ward off the carjacker. The other units mentioned "Stopjack" , and "Stopaction" can also be foiled by opening the door while driving or not using the brake and by keeping the engine speed above limits by gunning the engine while in neutral. The carjackers and thieves study all possible flaws a system has and then they are prepared to foil it. None of the mentioned products and systems are foil proof except for our system the "HIJACK BUSTER" with Uswitch.
