Liked reviews, value for amount of sensors. Just prep surfaces first so both sides of sensor stay secured

Our alarm system salesperson talked us into getting glass break sensors instead of window sensors. After my parents recently experienced an attempted break-in at their house, we decided to purchase these for our windows to increase security while avoiding an increased monthly security payment. These stick firmly and the alarm is very shrill. We can hear them from accross our single story, 1665sqft home. Though you may not be able to do the same in a two story home, they’re still very useful if people are upstairs and need to know when a window is open. I read some reviews saying they are not loud enough… I have hearing loss and I still think these are enough to alert residents and scare off intruders. We definitely feel safer having these sensors. At first I thought they were defective, but then I read the instructions (DUH…) and I realized there’s a small plastic battery block that needs to be removed before turning on. Just in case anyone else is like me and ignores instructions. So far, I would definitely recommend!

This product was purchased to keep my little escape artist inside the house. We installed locks he can’t reach but, since other people go in and out, there’s no way to guarantee they stay locked ALL the time. This handy device helps fill the gap by making sure mama knows EVERY time someone goes through the door!It’s VERY easy to install — if you don’t have any trim around your door. If you have trim, you’ll need to either forego the alarm or cut into the trim to make a space, because this needs to sit flush. But assuming you have the space for it, just make sure the area is clean and dry and stick it on with the (included) adhesive foam strips.It comes with batteries already installed; you’ll just need to remove the piece of plastic preventing them from making contact so they don’t burn out prior to purchase. They are, however, some weird button batteries, so when it’s time to replace them, they can’t be replaced with a trusty AAA.The overall device — both pieces — is a little smaller than I had anticipated. I’d say it’s a little smaller than two side-by-side boxes of matches. It has three settings: off, alarm, and chime. Off is pretty self-explanatory. I assume if it’s set to alarm, it will go off continuously when the door or window is opened. We keep it set on chime, so it goes off once every time the door is opened. It makes a very loud, obnoxious digital chiming sound; you’ve probably heard it if you’ve ever been in a store that announces your presence with an electronic chime. It isn’t a very pleasant sound if you’re standing right beside it, but I’m able to hear the downstairs door from upstairs, so there are benefits to its being as loud as it is.I wish it were designed to use a AAA battery, because the button batteries are exceptionally hazardous around children, but I have no complaints about the alarm’s functionality.

These are easy to install and are great for peace of mind with young children
