It's very reasonably priced and the sound of each alarm is so unbearably loud and high pitched that I'm confident that it would scare away any intruder

Great product for a good price

Great price, easy to use and very loud!

very loud, and a nice price

effective and reasonably priced

Functioned correctly at a reasonable price

They work great and at a great price as well.

Work as described... great price

I got extra batteries since they run down pretty quick after they go off, but the batteries were really a good price on here too.

Excellent price.

And the price is perfect for a single mom on a tight budget!I feel much safer now with one on every window!Highly recommend it!

Good price!!

Great price.

Also when you are home and they fall off it scares the cr@p out of you because you don't know if someone's touching the door or window or if it fell off

Not quite as loud as I
