Review on 🚨 DOBERMAN SECURITY Ultra-Slim Window Alarm - 100dB Alarm, Vibration Sensors - Sleek & Thin Design, Fits Any Window - Ideal for Home, Office, Dorm Room, RVs - SE-0106 by Rusty Smith

shrill, distinctive siren-like sound to deter an intruder slamming or slamming the window or a door. The minimum you should have if you think you need something. I've been using it for a few years now and have bought more. One that often triggers when cleaning or opening windows needs batteries, they are easy to replace and continue to work normally. So there's no reason I can't use it for a few more years or even more. The adhesive is strong and sticks for years and allows for easy access to change batteries. For the price this is a great value product that gives you a much more expensive full alarm system.
