Bests & Worsts Reviews from Amazon

So here’s the deal. These things are a great addition to any home security system, or a great deterrent if this is the only security you have. Most home break in thrives do not want to be seen or heard. They also know there is no way to beat a stand alone window break sensor. If they see this in your front window they are just going to go somewhere else. And to me the blinking led is the best feature of this device. It’s a beacon to the thieves saying “I will hear you”. 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.
