Super Door Stop

Product ID: DSAL-2
Use this wireless alarm to block a door from being opened. If anyone does try to open door, the 125-decibel alarm feature will sound. There is also a movement sensor with adjustable sensitivity to activate the alarm if tampered with! Great for hotel and dorm rooms as well as home. An on/off switch allows the alarm to be turned off so that it doesn't go off in your luggage. Requires one 9V battery (not included).
