When I moved out of my parent’s house to go to school, it was in a completely different city ninety miles away. There were no family members living nearby or friends I could call. Help, except the police, was literally over an hour away. Until I got to know the neighborhood better (and how well can you ever get to know your neighborhood, with people moving in and out all the time) and became familiar with it’s particular night noises, I would frequently be awakened by what seemed to be odd sounds.
If my kids were placed in the same situation, I would make sure they had the Super Door Stop Alarm. This item is wedge shaped, so a person only has to place it under the door. If an intruder manages to pick the lock and open the door, the wedge shaped door stop alarm will keep the door from opening. It will also sound an alarm of 120 dB which will not cut off until someone turns it off. There is also a movement sensor which can be adjusted to low, medium, or high that can activate if the alarm is tampered with.
One of the best features in my opinion is that there is no installation required. If you are at home, you put it under your own door. If you are traveling, you turn the door stop alarm switch off, easily located on the back, drop it into your purse or luggage. It is lightweight, coming in at less than half of a pound and only measures at 5 1/2 inches in length. When you have reached your destination and are settled in, you put it under the door, flip the switch on, and sleep soundly. It only requires a 9 volt battery.
Definitely one of my favorite products.
