Great for home security and traveling

Home feels more secure because if someone is breaking in I know and can arm myself. It also may scare whoever is breaking in. Great buy!

Great for home or travel!

Great product to keep intruders out of my home or my hotel room while vacationing. I like to travel and this is a great product that will likely scare intruders away with the noise. It takes one 9-volt battery for the alarm and it has an on/off switch. This door stop
could even be used without the battery if need be. I have used plastic/wood/rubber doorstops in the past "hoping" they would help in an emergency but now I know I will feel more comfortable, especially when away from home!


This door stop alarm will scare off intruder within first 1/2 inch of door opening, then stop opening door so they can 't come into house. I am very pleased. My single girlfriend was using a chair on the door in her condo but, now uses the door stop alarm I gave her. I will buy more..

Perfect for travel

I travel for work and am always concerned about hotel rooms. This is perfect. Very loud alarm - loud enough to wake the dead! Perfect to hopefully scare someone off who might try gaining access. If not, it would give some precious seconds to grab something to defend yourself. I'm very happy with this purchase.

Perfect for what I need

I live in an apartment by myself and wanted just something by the door. This little stopper works great. The noise is ridiculous loud and I've tested it and it will stop the door from opening. Makes me sleep a little better at night.
