Loud
We were able to hear the alarm at the other end if the house. We use it to alert the caregivers , it doesn’t seem to bother our lady but atleast they know if she’s on the move. My friend used them for her autistic son and he would immediately shut the door worked to deter him from exiting the home

These alarm sensors work just fine.
we have a 4 year old grand daughter that we don't go out in the yard by herself, as we have a pool. Installing these alarms are very simple as they are wireless. They are very loud for their size, with a simple on-off switch that we turn on when we have our grand daughter over. This is an inexpensive gadget that does the trick, and enhances safety.

Good cheap burglar alarm. Useless door close warning
The door close warning mode has no delay at all. The alarm starts going off immediately when you open the door. This mode is supposed to help when you forget to close the door. Not go off immediately.

Multiple Uses
I gave one to my grandma to carry in her pocket book just in case she feels unsafe or in a place somewhere out and about and needs help.. its fits in my kids bookbags and under my pillow for now..I have to find some extra sticky tape to hold mines in place but until then it's useful in other ways. You can take them with you on vacation in a hotel room or anyway for that matter. Cars too..

Need tools to use
This thing is ridiculous. It comes with tiny screws that need to be pulled out to put three tiny button batteries in the unit. I didn’t have a screwdriver, the time, or patience to do this. My eyesight isn’t the greatest either. Returning.
