## Description

This slim, modern shock sensor alarm triggers a 130dB siren if a potential intruder attempts to hit or smash the window. Easy to install, an effective burglar deterrent.

Review: I love it. - I only got it today and stuck them on the bottom right of the downstairs window glass and gave it a few knocks and boom, the alarms went off. Imagine how quickly it would go if a hard object were to hit the glass! So far, so good. And I like how it has the warning sticker to alert intruders. Great product and easy to use, not to mention the slim design and great adhesive. Not expensive and well packaged. Sensitivity is great as the goal is to be alerted for break in or broken glass, not tapping on the glass.
Review: Good loud noise if activated. - Great price. Makes a very good loud alarm if activated. Have placed on all windows.
