【Durable and High Quality】The door stop alarm is made of high-quality ABS plastic and stainless steel plate. Excellent performance in terms of quality and service life. Note: the gap between the door and the floor must be at least 10-35 mm for normal operation. 【Easy Operation】There is an ON/OFF button on the door stop alarm. Simply place the alarm under the door and turn on the switch to activate it. As soon as an intruder attempts to enter, the door stop alarm will immediately trigger and emit a 120dB alarm. 【Adjustable Sensitivity Levels】Adjust the sensitivity of the door security alarm - low, medium, and high. Choose the levels according to your needs. Set the volume to high while you sleep and you'll be aware of the subtle differences in your door's noise level, giving you peace of mind. 【Excellent Design】The shock-absorbing rubber at the bottom prevents the door from sliding when someone pushes on it. Remember to push it firmly under the door when using it. It is not recommended for use on very smooth floors (such as tile/laminate/wood) or to adjust the sensitivity level to a high setting if necessary. It can be used as a regular doorstop when the switch is off and holds the doors in the correct position. 【Protect Your Safety】Requires only one 9V battery (NOT included). Lightweight (110g)/pack and convenient to carry, it protects your safety whether you are at home or traveling. It is best used on doors that open inwards (such as in hotels).
