So how does it work? I have added a video showing me measuring the sound levels compared to the claims. My meter measured 115DB right next to the unit. That’s close enough to call the claim accurate. The video also shows the sound dissipation as you move away. The sound level is cut in half at about 10 feet. But unless you are a very heavy sleeper wearing earplugs, you are probability going to hear this go off in the dead of night.
The fact that you get 4 for 25.00 is just icing on the cake. Put two facing the street In very visible places and two in the back on your sliding doors or windows. I am probability going to get another 4 to cover the rest of my windows. This is really a good product and I would definitely recommend it.
FYI: I paid full price for this product and was not given any consideration for this review. In fact I search for “window break sensor” here on amazon and this showed up. Glad I found it. If you found this review helpful please indicate so below.
