If you travel along a lot and worry about your safety while staying in hotels or AirBnBs, sometimes the locks that are already built-in to the door just don’t make you feel safe enough. This unique portable door lock called the DoorJammer lets you lock any door by quickly installing it to the base of a door. Once installed, it prevents anyone from entering the room without first breaking down the door.
