they are easy to install
The reason I bought this product is because the neiborhood I live is not very safe. I used this on my front door and back door, even my windows. The sound of alarm is very large, I can haer it from outside. Also, they are easy to install. Just peel the seal and stick them to the doors and windows. Nice product makes you feel safe at home.

LOUD. Warns me when one of the grandchildren try to escape. I first bought these because of having a pool that tempted the children to try and go out and see without supervision. Downside is once in a while the sticky tape will let go and it will alarm in the middle of the night and scare me.

8 out of 10 work great and one is bad and one about to go bad. Flimsy plastic but these units do what they suppose to do. expect few defective pieces. Seller never sent the replacement.

Not all of these worked.....
Two did not work right out of the bag. One that did work fell off the window seal in 3 days. The ones that work are as described.
