It is easy to put on and makes a shrill loud noise.

It works so well with super high pitch alarm noises which is intolerable, for human beings and animals

Just installed them and the noise is very recognizeable and will scare off anyone

Don't forget to turn them off when you're about to open your door and leave for work because it's not a pleasant noise to hear first thing in the morning!

Then, I heard a strange chirping noise

I just need to know when someone goes out or in....if you need a loud noise, these would be the alarms to purchase, if you want a nice chime, these are not your alarms

The loud noise scared my kids and they stopped messing with the door.

Easy to use but the noise is so loud

Plus for our situation the noise scares the cat away from the door when it does open too

The noise will scare off any intruder,and make you instantly aware of that door or window

These are a damn nice noise maker.

The noise these alarms make is INCREDIBLY loud.

That is because after they pass inspections, most people turn them off because they don't like the noise.

Wife doesn't like the noise, but I like my stuff!

If you feel the noise is too loud when you are near the door, you can turn it off

They make a hideous noise and wont stay in place

The other one makes this awful chirp sound on chime and an even odder noise on alarm mode

Definitely makes enough noise that it would make someone think twice about entering
