MACE WINDOW ALERT is a 95 dB glass breakage alarm that attaches to windows and is set off by vibrations caused if someone tries to break through. Installs easily on any window. Solid, state-of-the-art design. Battery included.

I have had this product for 12 years. It triggers if I get too close with the lawn mower, or loud thunder. Works very well as intended. Battery replacement is challenging (I need readers), but I have only replaced them twice in 12 years. I think they are great.
