Greeting for intruders

I bought this so that we could have some assurance that someone trying to come in our doors uninvited would have a "greeting" when they might try to enter. Wow, loud enough to scare off anyone. We plan to use them when out of town as well. Easy to use.

WOW, the price of these has come down. ...

WOW, the price of these has come down. The loudness is the same and the quality is the same. The one I bought several years ago burned out because someone used it as a doorstop- ugh! I take it with us when traveling and use it whenever I need a higher level of warning at our door. There is NO sleeping through this alarm.

Works great, no slip pads on bottom, great way to feel safer anywhere with a door!

We just received ours, and it works great on our linoleum floor, doesn't slide at all and the floor is a very slick smooth surface, no texture on the floor at all. The door stop has a textured rubber pad on the bottom which does a lot to help it not slip. I tried it on our door several times without turning it on and worked great every time, stopped the door and the alarm would have went off if I had it turned on!
The battery door was really hard to get open, kept thinking I was going to break it, but eventually after working hard at it I got it open. Takes one 9V battery which is a tight fit but just push hard and it will go in. The siren is VERY LOUD, so when testing it to make sure it worked I bunched a winter coat over top of it so not to bother neighbors.
I think this is a great way to feel safer in your home, apartment or motel room!!! I'm going to order 2 for my daughter who lives by herself, hopefully she'll use it!!

The item was as expected and as described!

We are quite happy with the product, the seller and the shipping. The item(s) were as expected and as described! Perfect if all you want to add to a door, like the backyard door, and know when someone opens it. It's loud enough for us, we can hear the alarm from our bedroom and office, which is what we wanted the product to do for us. We tested the 3 units, worked as described. These units are not extremely loud, but read the description before buying and later saying they're not loud enough. For the price, we do not expect them to deter, but to let us know someone has opened a door or the doors where they are in place.
