The Portable Door Jammer is an ingenious invention that provides the user with "privacy, security and peace of mind."
Looking almost like a miniature car jack, the Portable Door Jammer is a device that secures to the bottom of most door frames as well as on most surfaces. The clever design of this particular door stopper "increases the Door Jammer's grip and reduces the chance of the foot slipping," ensuring that anyone trying to enter the room will have a tough go of it.
Besides teenagers who don't want their parents entering their rooms without knocking, the Portable Door Jammer is primarily for travellers, the elderly and women who face a greater need at times for security and peace of mind. The Door Jammer is no bigger than an iPhone, making it easy for you to bring it wherever you feel you'll need it most.
