I often stay in hotel rooms on my own and feeling safe and secure = a good night’s sleep. Short of jamming a chair under the doorknob, this door-stop alarm does the trick securing any hinged doors.
With non-skid strips, it doesn’t move easily. Any motion in the doorway instantly sets off a pulsating, ear-splitting siren alarm guaranteed to scare any would-be burglars away. Uses two AA batteries and operates with an easy on/off switch. Compact enough to tuck in your suitcase for complete ease.
