Door Stop Alarm, Door Stopper with 120DB Security Alarm, Floor Wedge Doorstop for Travel Apartment Home House (Pack of 1)

It is simple to operate. Buzzer is loud, light and smaller than the average sized hairbrush.

Fits great, good for security, holds the door well, easy to install, easy to use. Very durable!

So simple to use. The tone omitted from this simple device is almost deafening! I am a sound sleeper but feel certain if an intruder tried to enter my home I would be awakened. Also that intruder would split assuming this was a home alarm system. The device is placed at the door on the floor, it has rubber feet that grip the floor, as the door is pushed open the door hits the plate on the device and it triggers the alarm blast of intense sound. A great security tool for a small price.

Works well it’s loud enough to awake you small enough to fit in a carry on worth the money and easy to use

The door stopper alarm works very well. It's very loud!!!

Item was just as described - and way louder than I thought it would be. Great for Hotel rooms or scaring off your children's hungry friends looking for leftovers! The nonstick pad on the bottom keeps it in place on wood floors.

Works great but the hotel/cruise/room has to have carpet it doesn’t work if it’s title which most are these days.

So loud! There's no way you can't hear it. Fits perfectly under my door very sturdy.
