Home invasions are dramatically on the rise everywhere. The FBI says that a home is invaded once every 12 seconds. Burglars mainly just "kick in" doors. They can usually get through your door in less than 1 second with one good well placed kick. It happens most often due to door frame failure. Wooden door frames simply can't hold up to the impact. There is a product called the Door Security Pro that prevents home invasions due to door kick-ins. It's easy to install and lasts forever. It's available online from: http://www.DoorSecurityPro.com
