Slide one behind your hotel or rental door before bed. If someone pushes the door, a 120dB siren goes off and the rubber base helps hold the door in place.
Why it's worth packing
Stops and alerts: A rubber base grips the floor to help hold the door, and the alarm sounds the moment the door is pushed.
Loud 120dB siren: Loud enough to wake you and draw attention fast.
Adjustable sensitivity: High, medium, and low settings help cut down on false alarms.
No installation: Place it behind any door that opens into the room. Works with door-to-floor gaps of about 0.6 to 1.2 in.
Four in the pack: One for your travel bag, and spares for home or for family.
