The sticker on the backside is an effective visual deterrent as well

I would recommend this product because it is easy to install and a nice deterrent.
-
Great visual deterrent though.
-
Simple, effective, security deterrent
-
Cheap anti theft deterrent and a great buy.
-
Good deterrent.
-
I like having these as an extra deterrent for someone thinking of breaking in, and have used them on doors that could be pried as well

These cost effective devices are a good first line deterrent, when backed up by a real security system.
-
Not the best security, but a deterrent.
-
For the price this is a great deterrent.
-
Its a great deterrent.
-
Wish it was a bit louder, but hopefully a great deterrent if neighbor just doesn't happen to hear it
-
These are wonderful as a deterrent for a possible home invasion -
-
Nice little security deterrent to add to the house.
-
A great noise deterrent and will scare off anyone trying to break-in
-
BUT... it may be a helpful deterrent thanks to the sticker that shows through the window outside
-
This is a nice deterrent for burglars
-
The side that faces out the window also has a warning on it that the window is alarmed, which I find comforting as a deterrent for someone lurking around the house.
-
Perfect low-cost security deterrent
-
Adds an extra layer of security and is a good deterrent to burglars when they see the dog decals.
-
So far they are a great deterrent, just a shake on the window to test if it is locked sets off an ear piercing siren that runs 30 seconds then resets.
