Securing rooms from unauthorized entry couldn't be easier. The Personal Security Door Stop Alarm requires no wires or complicated installation and is powered by 1 x 9V battery (not included). Simply place the pressure-sensitive Door Stop Alarm at the base of any door, and the device will emit a powerful 120-decibel alarm when the door is opened. The Door Stop Alarm is extremely compact, so it's convenient enough to take anywhere. With this handy gadget, you'll be able to secure your hotel room, dorm room, apartment, or any room in your home.
The Deluxe Door Stop Alarm uses very soft and full area rubbers, so it can stop any doors even used on very slippery floor. When traveling, just toss this lightweight unit in your luggage. Simply place the alarm behind any door. If an intruder attempts to open the door, the wedge-shaped design of the unit will prevent it from opening and activate a 120 dB alarm, which will scare off the intruder and alert you to the attempted entry.
